The ATARAustralian Tertiary Admission Rank is the single most important number in an Australian high school student's academic life. This percentile rank—ranging from 0 to 99.95—determines university course eligibility, scholarship opportunities, and for many students, their sense of self-worth during one of the most stressful periods of their lives. Yet despite its importance, most students approach ATAR preparation without a systematic plan.
Here's what separates students who achieve their target ATAR from those who fall short: it's rarely about intelligence. The difference almost always comes down to study efficiency, strategic subject selection, and consistent effort over time. This guide will show you exactly how to prepare for your ATAR using evidence-based strategies and systematic time tracking—whether you're targeting 80, 90, 95, or 99+.
The difference between an 85 and a 95 ATAR almost always comes down to study efficiency, not raw intelligence. Smart preparation beats talent without discipline.

How many hours do you need for your target ATAR?
This is the question every Year 12 student asks. The answer depends on your starting point, your natural aptitude for your chosen subjects, and your target rank. But research and data from high-achieving students provide reliable benchmarks.
Weekly study hours by ATAR target (outside school hours):
| ATAR Target | Weekly Hours (Terms 1–3) | Weekly Hours (Final Term) | Total Year 12 Hours |
|---|---|---|---|
| 70–79 | 8–12 hours | 15–20 hours | 400–550 hours |
| 80–89 | 12–18 hours | 20–28 hours | 550–750 hours |
| 90–94 | 15–25 hours | 25–35 hours | 700–950 hours |
| 95–98 | 20–30 hours | 30–40 hours | 900–1,200 hours |
| 99+ | 25–35 hours | 35–50 hours | 1,100–1,500 hours |
These aren't arbitrary numbers. They reflect the reality that ATAR is a competitive ranking—to reach the 90th percentile, you need to outwork roughly 90% of your cohort. The good news is that these hours are spread across an entire year, making consistent daily effort far more manageable than last-minute cramming.
Why tracking your hours matters
Most students dramatically overestimate their study time. They count hours spent "at the desk" rather than hours spent in focused learning. Actual focused study—without phone interruptions, social media, or aimless re-reading—is often 40–50% less than perceived study time.
This is why time tracking is essential. When you track your actual study hours with a tool like Athenify, you get honest data about your preparation. You might discover you're studying 12 hours a week when you thought it was 20—and that gap explains why your results aren't matching your effort.
Students who track their study time accurately outperform those who estimate, partly because tracking reveals the uncomfortable truth about how much focused work is actually happening.
Understanding proper time management as a student can transform your ATAR preparation from chaotic cramming into systematic progress.
Understanding subject scaling
Subject scaling is one of the most misunderstood aspects of ATAR calculation—and one of the most strategically important.
How scaling works
Your raw exam score is adjusted based on the performance of students who took that subject. Subjects typically taken by high-achieving students (like Specialist Mathematics, Physics, and Chemistry) scale upward, while subjects with lower-performing cohorts may scale down.
Typical scaling effects by subject category:
| Subject Type | Example Subjects | Typical Scaling Effect |
|---|---|---|
| High-scaling | Specialist Maths, Physics, Chemistry, Languages | +5 to +12 points |
| Moderate-scaling | Methods, English, Biology, History | +0 to +5 points |
| Low-scaling | Foundation subjects, some VET courses | -2 to -8 points |
Strategic subject selection
The optimal strategy isn't to maximise scaling—it's to maximise your scaled scores. This means choosing subjects where you can achieve high raw scores (your natural aptitude matters), benefit from reasonable scaling (avoid the lowest-scaling subjects if possible), and maintain genuine interest (you'll study more effectively in subjects you enjoy). The interplay of these factors determines your optimal subject mix far more than any single consideration.
For most students targeting 90+, the ideal combination includes at least one mathematics subject (Methods or Specialist), at least one science (Physics, Chemistry, or high-level Biology), English (which is required in most states), and one or two subjects aligned with your strengths and interests. This balance captures scaling benefits while ensuring you're studying subjects where strong performance is achievable.
Creating your Year 12 study schedule
Effective ATAR preparation requires different strategies at different times of the year. Here's how to structure your Year 12 journey.
Term 1: Foundation building (February–April)
Focus: Content mastery, establishing routines, identifying weaknesses
| Weekly Priority | Time Allocation | Activities |
|---|---|---|
| Class content | 8–10 hours | Homework, readings, consolidation |
| Active review | 4–6 hours | Active recall, flashcards, practice problems |
| Weak areas | 3–5 hours | Extra work on challenging concepts |
During Term 1, your primary goal is mastering new content as it's taught. Don't fall behind—it's much harder to catch up later. Establish a consistent daily study routine, even if it's just 2–3 hours on school nights.
Term 2: Skill development (April–June)
Focus: Deepening understanding, beginning revision, practice questions
This is where preparation intensifies. You should now be comfortable with your subjects' content and shifting toward application and exam technique.
| Weekly Priority | Time Allocation | Activities |
|---|---|---|
| Content consolidation | 6–8 hours | Reviewing earlier topics, filling gaps |
| Exam technique | 6–8 hours | Practice questions, timed exercises |
| Spaced repetition | 4–5 hours | Reviewing previous terms systematically |
Use spaced repetition to review Term 1 content while keeping up with new material. This prevents the common problem of forgetting earlier topics by exam time.
Term 3: Trial exams and intensive revision (July–September)
Focus: Practice exams, weakness remediation, exam conditions
Trial exams (or mid-year exams, depending on your state) are crucial—they often contribute to your final score and provide realistic exam practice.
Trial exams are dress rehearsals. Treat them with the same seriousness as the final exams. The habits you build here carry into October and November.
| Weekly Priority | Time Allocation | Activities |
|---|---|---|
| Practice exams | 8–10 hours | Full papers under timed conditions |
| Exam review | 6–8 hours | Analysing mistakes, refining technique |
| Targeted revision | 8–12 hours | Addressing weaknesses revealed by trials |
Complete at least 2–3 full practice exams per subject during this term. More importantly, spend significant time reviewing each exam—understanding why you got questions wrong is more valuable than simply completing more papers.
Term 4: Final preparation (October–November)
Focus: Consolidation, confidence building, exam execution
Your study intensity should peak in the weeks before exams, then taper slightly in the final days.
| Week | Weekly Hours | Primary Focus |
|---|---|---|
| 3–4 weeks out | 35–45 hours | Intensive revision, full practice exams |
| 2 weeks out | 30–40 hours | Targeted weakness review, exam technique |
| Final week | 20–30 hours | Light review, confidence building, rest |
Subject-specific preparation strategies
Different subjects require different approaches. Here's how to maximise your study efficiency across the major ATAR subject areas.
Mathematics (Methods, Specialist, General)
Mathematics is cumulative—every concept builds on previous ones. This makes consistent practice essential. You should solve problems every day, even if just for 30 minutes, because mathematical fluency erodes quickly without regular use. When reviewing solutions, don't just check whether you're right—understand the method deeply enough that you could explain it to someone else. Building a formula sheet, even if you can't use it in exams, reinforces memory through the act of creation and organisation. And timing your practice matters enormously: exam time pressure is real, and students who only practise untimed often freeze when the clock is ticking.
For detailed mathematics study strategies, see our guide on how to study math effectively.
Sciences (Physics, Chemistry, Biology)
Science subjects combine conceptual understanding with application. Many students make the mistake of only reviewing content without practising exam-style questions—they understand the theory but struggle when faced with unfamiliar problem formats.
The key is understanding rather than memorising: focus on why phenomena occur, not just what happens. When you understand the underlying principles, you can apply them to novel situations rather than relying on pattern-matching to questions you've seen before. Start practicing calculations early in the year rather than leaving quantitative work until exam time, when the pressure makes learning new skills nearly impossible. Past exam questions are particularly valuable for science subjects because examiners often repeat question styles and test the same concepts from different angles. Creating concept maps that link related ideas across topics helps you see the bigger picture and answer questions that integrate multiple areas—a favourite examiner technique.
Our biology study guide covers strategies that apply across all science subjects.
English (Standard, Advanced, Literature)
English is unique because it's required for ATAR calculation in most states and is notoriously difficult to "study" in the traditional sense. Unlike mathematics or sciences, there's no formula sheet to memorise or set of problems to drill.
The path to English excellence runs through reading widely—exposure to sophisticated writing improves your own, even when you're not consciously analysing technique. Essay writing is a skill that develops only through practice under time pressure; you can't think your way to good writing without actually writing regularly. Know your texts deeply, because surface-level knowledge won't survive exam pressure when you need to recall specific quotes and analyse subtle themes. Perhaps most importantly, get regular feedback—have teachers or tutors review your essays, because it's nearly impossible to identify your own blind spots.
Humanities (History, Economics, Legal Studies)
Humanities subjects reward deep understanding and the ability to construct arguments under time pressure. The challenge isn't usually the content itself—it's expressing that content persuasively within strict time limits.
Mastering essay structure is essential because clear arguments beat extensive knowledge presented poorly. Examiners can't give marks for ideas trapped in your head; they can only mark what appears on the page in coherent form. Top marks require understanding multiple perspectives and engaging with nuance—superficial one-sided arguments cap your potential. Use active recall by testing yourself on key concepts rather than passively re-reading notes, which creates an illusion of competence without building genuine retrieval strength. And practice timing religiously: humanities exams often require managing time across multiple extended responses, and students who run out of time on their final essay lose marks they could have easily earned.
Practice exam strategies
Practice exams are the cornerstone of ATAR preparation. They're not just assessment—they're the most effective learning tool available.
How many practice exams should you complete?
Recommended practice exams per subject:
| Time Period | Number of Full Exams | Purpose |
|---|---|---|
| Term 2 | 1–2 | Familiarisation, early diagnosis |
| Term 3 | 3–5 | Intensive practice, trial exam prep |
| Term 4 | 2–3 | Final consolidation, confidence building |
| Total | 6–10 | Comprehensive preparation |
The review process
Completing a practice exam is only half the work. The review is where actual learning happens.
For every practice exam, spend at least equal time reviewing. Mark your paper honestly using official marking criteria where available—self-deception about your performance helps no one. Categorise your errors into content gaps (you didn't know the material), careless mistakes (you knew it but executed poorly), or time management issues (you ran out of time before demonstrating your knowledge). Understanding correct answers means going beyond noting what's right to understanding why it's right and why your answer was wrong. Finally, create an action plan that specifies what study will address each identified weakness. Without this systematic review process, practice exams become exercises in reinforcing bad habits rather than opportunities for improvement.
The students who improve most aren't those who complete the most practice exams—they're those who review each exam most thoroughly.
Simulating exam conditions
Practice under realistic conditions to build the stamina and composure you'll need on exam day. Enforce full time limits with no extensions and no breaks outside allocated reading and writing time. Resist the temptation to check notes mid-exam, even "just quickly"—this habit undermines your ability to perform without a safety net. Create an exam environment with a quiet space, a clear desk, and your phone in another room entirely. And since most exams run in the morning, train your brain for that timing by scheduling your most serious practice sessions before lunch. Students who only study in the evening often find their mental acuity surprisingly diminished during morning exams.
How Athenify helps with ATAR preparation
Achieving your target ATAR requires consistent effort over an entire year. The challenge isn't knowing what to study—it's maintaining discipline when motivation fluctuates.
Try Athenify for free
Track every study hour across all your ATAR subjects. See exactly where your time goes, build consistency with streaks, and ensure your effort matches your ambitions.
No credit card required.
No credit card required.
Athenify helps ATAR students by tracking study hours by subject, so you can see whether you're actually spending 60% of time on weak areas or just telling yourself you are. The streak feature builds momentum through visual consistency tracking—when you can see a 30-day streak on the line, skipping today's study session becomes much harder to justify. Perhaps most importantly, Athenify provides honest data: no more guessing how much you've studied, no more inflated self-estimates. Weekly reviews comparing planned versus actual study hours reveal the gaps between intention and execution, giving you time to course-correct before those gaps become insurmountable.
The Pomodoro technique integrates perfectly with time tracking—each 25-minute session becomes a recorded unit of focused work.
Common ATAR preparation mistakes
1. Starting too late
Many students don't begin serious preparation until Term 3 or even Term 4. By then, there's not enough time to build deep understanding—only surface-level cramming remains possible.
The fix: Establish consistent study habits from Term 1 of Year 12, even if intensity is lower initially.
2. Ignoring subject scaling
Choosing subjects purely based on perceived difficulty or interest, without considering scaling effects, can cost 5–10 ATAR points.
The fix: Research scaling for your state and factor it into subject selection—but don't choose subjects you'll struggle in just for scaling.
3. Not tracking study time
Without tracking, students consistently overestimate their study hours by 40–50%. They feel they're working hard but results don't match perceived effort.
The fix: Track every study session honestly. The data reveals where your time actually goes.
4. Passive revision
Re-reading notes and highlighting textbooks feels productive but produces minimal learning. It's comfortable, not effective.
The fix: Use active recall and spaced repetition. Test yourself constantly instead of passively reviewing.
5. Neglecting weak subjects
It's natural to study subjects you enjoy and avoid those you find difficult. But your weakest subjects often have the most room for improvement.
The fix: Allocate 60% of study time to your weakest subjects. The marginal gains are largest where you're currently scoring lowest.
6. Poor exam technique
Strong content knowledge means nothing if you can't express it under exam conditions. Many students lose marks to poor time management, incomplete answers, or misread questions.
The fix: Practice under exam conditions regularly. Learn to allocate time based on marks available, and always read questions twice.
The final weeks: Trial exams to HSC/VCE/QCE
The transition from trial exams to final exams is critical. Here's how to use your trial results effectively.
Analysing trial exam performance
After trials, conduct an honest assessment:
| Question | Action if Yes |
|---|---|
| Did I run out of time? | Practice timing; consider question order strategies |
| Were errors mostly careless? | Slow down; build checking habits |
| Did I struggle with specific topics? | Targeted revision; consider tutoring |
| Was my essay structure weak? | Practice essay plans; get feedback |
The final four weeks
Week 4 before exams:
- Complete one full practice exam per subject
- Intensive revision of weak topics identified in trials
- 35–45 hours of study
Week 3 before exams:
- Focus on past exam questions, not content review
- Address any remaining knowledge gaps
- 30–40 hours of study
Week 2 before exams:
- Light practice—maintain skills without exhaustion
- Review common mistakes from all practice exams
- Begin reducing caffeine if you've been using it heavily
- 25–35 hours of study
Week 1 before exams:
- No new content or intensive revision
- Light review of key formulas, quotes, and concepts
- Focus on sleep, nutrition, and exercise
- 15–25 hours of study
Test day strategies
All your preparation culminates in exam day performance. Here's how to maximise your results.
The night before
The night before an exam is not for cramming—it's for preparation and rest. Do only light review, then deliberately relax. Prepare everything you'll need: calculator (with fresh batteries), pens, ID, water, and any permitted materials. Set multiple alarms, because missing an exam is simply not recoverable. Get to bed early enough to allow 8+ hours of sleep; the consolidation that happens during sleep is more valuable than any last-minute cramming.
The morning of
Eat a proper breakfast with complex carbohydrates and protein for sustained energy—you need fuel that won't spike and crash mid-exam. Arrive early, because being rushed increases anxiety and clouds your thinking before you've even started. Light review can help if it settles your nerves, but stop at least 15 minutes before exam time to let your mind clear. Handle your bathroom break before entering the exam room; leaving during the exam wastes precious minutes and disrupts your concentration.
During the exam
Read all instructions carefully, even if you think you know what's coming—don't lose marks to misunderstood requirements. Allocate your time by marks: a 10-mark question deserves twice the time of a 5-mark question, so do the arithmetic before you start writing. Begin with questions you know well to build confidence and momentum, but don't get stuck on any single question—move on from difficult ones and return later with fresh eyes. Show all your working, because partial marks require visible reasoning that examiners can follow. Budget 5–10 minutes at the end for reviewing your answers; this time investment catches careless errors that would otherwise cost you marks you've already earned.
Exams test what you can demonstrate under pressure, not just what you know. Practice performing under time constraints, not just knowing the content.
After each exam
Resist the temptation to discuss answers with classmates—it only creates anxiety you can't act on, and you'll second-guess yourself about questions you probably got right. Focus forward: the next exam matters, while the previous one is already done and unchangeable. Do light review for tomorrow's subject, but don't neglect rest; exhaustion accumulates across exam weeks and impairs performance more than insufficient study. When it's finally all over, celebrate properly—you've earned it, and your brain needs genuine downtime to recover from sustained high-intensity effort.
The long view: ATAR in perspective
Your ATAR matters—but it's not the only path to your goals. Alternative pathways, transfers, and graduate applications mean that a lower-than-hoped ATAR rarely closes doors permanently.
That said, putting in the effort now is almost always easier than finding workarounds later. The habits you build during ATAR preparation—consistent study, time management, working under pressure—will serve you throughout university and beyond.
