A 90 ATAR sounds super intimidating. When I was completing Year 12, it felt like the number belonged to a completely different category of student: the people who came first in every subject, started studying six months early and somehow never procrastinated.
That was not me.
Throughout Year 12, I regularly felt as though I was underperforming. I compared my marks with the strongest students in my classes, focused on every question I got wrong and assumed everyone else understood the ATAR system better than I did.
I eventually received an ATAR of 92.
I was obviously happy, but my first reaction was mostly surprise. My internal picture of a “90 ATAR student” had been someone nearly perfect. My actual experience was much less impressive: I worked consistently in some periods, fell behind in others, had assessments I was proud of and had assessments I preferred not to discuss.
So, is a 90 ATAR hard to get?
Yes, but probably not in the way you think.
A 90 ATAR is a strong and competitive result. It requires you to perform well across your subjects and generally remain consistent over Year 12. However, it does not require perfect marks, a flawless assessment record or twelve-hour study days.

What Does a 90 ATAR Actually Mean?
The first thing to understand is that an ATAR is a rank, not an average mark.
An ATAR of 90.00 means that you performed well enough to be placed ahead of approximately 90% of your age group. It does not mean you averaged exactly 90% across your HSC subjects.
This distinction matters because students often imagine that a 90 ATAR requires five HSC marks above 90.
It does not.
In NSW, UAC calculates your ATAR using an aggregate of scaled marks from:
- Your best two units of English
- Your best eight remaining units
Your HSC marks are converted into scaled marks before they are used in this calculation. Scaling allows students completing different combinations of subjects to be compared fairly.
Because the ATAR is based on scaled marks and relative performance, there is no universal subject average that guarantees a 90 ATAR.
How Many Students Receive an ATAR Above 90?
By definition, an ATAR of 90 places you around the top 10% of your age group.
However, you may come across statistics showing that more than 10% of ATAR recipients achieve 90 or above. For example, UAC’s preliminary report for the 2025 NSW HSC stated that 17.3% of students who received an ATAR achieved 90.00 or higher.
This is not a contradiction.
The ATAR compares you with your broader age cohort, including people who did not complete an ATAR-eligible study program or did not receive an ATAR. The group of students who actually receive an ATAR is already a smaller and more academically focused part of the total age group.
From one perspective, 90 is extremely difficult because it places you near the top of the state.
From another, approximately one in six NSW students who received an ATAR in 2025 achieved 90 or above.
That is still a major accomplishment, but it is not a result reserved for five students sitting in the front row of every selective school.
Do You Need Band 6s in Every Subject?
No, and this is probably the biggest misconception I had during Year 12. I thought a 90 ATAR student needed to open their HSC results and see 90s across the entire page.
A Band 6 is an HSC mark between 90 and 100 in a two-unit course. However, your ATAR is not calculated by simply averaging the HSC marks displayed in your results. UAC uses scaled marks, and the relationship between an HSC mark and a scaled mark differs between courses and years.
A student may receive a 90 ATAR with a combination of strong Band 5 results and one or more Band 6 results. Another student might receive several marks above 90 but achieve a different ATAR because of their subject combination and the scaling applied that year.
You should certainly aim to maximise every mark available. However, receiving an 82 in one course does not automatically remove you from contention for a 90 ATAR.
Your best ten eligible units are considered. If you study more than ten units, one weaker course may not contribute at all, apart from the requirement that your best two English units must be included.
What Marks Do You Need for a 90 ATAR?
There is no completely accurate answer until the year’s HSC results have been processed.
Scaling changes each year because it depends on the academic performance of the students completing each course. Even if you correctly predict all your HSC marks, an ATAR calculator can only provide an estimate using historical data.
As a very broad goal, students aiming for a 90 ATAR should usually be working towards strong Band 5 performance across their contributing subjects, with higher results wherever possible.
However, avoid turning this into a rigid rule such as:
I need exactly 85 in every subject.
An 85 in one course will not necessarily contribute the same scaled mark as an 85 in another. Your final ATAR will also depend on which ten units become your best scaled units.
ATAR calculators can help you test different possibilities, but they should be used as planning tools rather than fortune tellers. UAC’s ATAR Compass uses scaling statistics from the previous five years and clearly warns that the result is only an estimate.
The healthiest way to use a calculator is to ask:
Roughly what standard should I be working towards?
The least healthy way is to enter every individual assessment mark after midnight and decide that your future career is over because the estimate dropped by 1.4 points.
Does Subject Scaling Decide Whether You Can Get 90?
Subject scaling matters, but students often misunderstand how much power it has.
Scaling does not exist to reward students for selecting subjects that sound difficult. It exists so UAC can compare students who completed different courses. UAC explains that scaling reflects the strength of the competition within a course, not its perceived difficulty.
A high-scaling subject is not automatically helpful when you perform poorly in it. Similarly, doing well in a course that scales lower can still make a strong contribution to your ATAR.
This is why choosing Mathematics Extension or Physics solely because someone told you they “scale well” is not always a smart strategy. A subject you understand, enjoy and can perform strongly in may contribute more than a supposedly impressive subject in which you consistently struggle.
A 90 ATAR is possible through many different subject combinations. Some combinations may make the highest possible ATARs more difficult, but students should not assume that humanities, arts or lower-scaling courses automatically prevent them from reaching 90.
One student on Reddit reported achieving a 97 ATAR without studying mathematics or science, despite describing their subjects as poor-scaling. This is only one person’s experience, but it demonstrates why strong performance matters more than blindly selecting stereotypically high-scaling courses.
What Do Past Students Actually Say?
Reddit discussions are not official ATAR advice. Students may be using different state systems, remembering marks inaccurately or simplifying complicated scaling processes.
However, these discussions are useful because they reveal how students genuinely experienced Year 12. The most common theme is not that a 90 ATAR is effortless. It is that students often imagined it would require far more perfection than it actually did.
The last example is particularly useful. The student initially posted results that another commenter estimated would produce an ATAR around 80. They later returned to report an ATAR of 94.45 after improving substantially, including reaching first place in Biology.
This does not mean every student can instantly turn an 80 estimate into a 94. It shows that early Year 12 marks do not permanently determine your final result. Rankings can change, study habits can improve and later assessments may reveal a very different level of performance.
Other Reddit discussions are much less optimistic. Some students correctly point out that achieving 90 means outperforming most people in your age group and requires genuine application.
Both perspectives can be true.
A 90 ATAR is not easy in the sense that you can ignore school for twelve months and confidently expect one. It is achievable in the sense that you do not need to be a genius, attend an elite school or earn full marks in every task.
What Actually Makes a 90 ATAR Difficult?
Consistency Matters More Than One Brilliant Result
You cannot usually rely on one strong subject to carry four subjects you have neglected.
A 90 ATAR generally requires solid performance across most or all of the ten units that contribute. You can survive a disappointing task, but repeated underperformance becomes harder to overcome.
This is where many capable students struggle. They are not unable to understand the content. Their effort simply arrives in bursts.
They study intensely before one assessment, burn out afterwards and then repeat the cycle. A 90 ATAR becomes much more realistic when your ordinary weeks are productive—not only the week before Trials.
You Are Competing Against Other Strong Students
An ATAR is relative. Improving your own marks matters, but your final rank also reflects how your performance compares with everyone else.
This is especially noticeable around higher ATAR ranges. Moving from an ATAR of 70 to 80 and moving from 90 to 95 are not equivalent challenges. As you move higher, you are competing against students who are increasingly consistent.
The difference may come down to avoiding preventable mistakes, producing stronger extended responses or converting knowledge into marks under timed conditions.
Exam Technique Becomes Important
Knowing the content is only part of the job.
To perform at a 90-ATAR level, you must also be able to:
- Interpret unfamiliar questions
- Identify what the marking criteria require
- Allocate time appropriately
- Structure extended responses
- Show sufficient working
- Avoid losing easy marks
- Perform under pressure
I had assessments where I knew the topic well but did not communicate that knowledge effectively. That was one reason I felt I was performing worse than I actually was: my mistakes felt obvious after the exam.
The students who improve most during Year 12 are often not learning twice as much content. They are becoming better at turning what they already know into marks.
Your Own Expectations Distort Your Perspective
At a competitive school, a student ranked in the middle of a strong class may assume they are doing terribly.
You may hear classmates discuss 95 ATAR goals, Extension subjects and unusually high marks until a result in the 70s feels like failure. In another cohort, the same result may place a student near the top.
This was one of my biggest problems. I judged my performance against the strongest person I knew rather than against the standard required for my own goals.
Feeling behind does not always mean you are actually behind.
What Does a Realistic 90 ATAR Student Look Like?
There is no single personality or study routine.
A realistic 90 ATAR student might:
- Receive mostly Band 5s and a Band 6
- Be excellent in two subjects and solid in the others
- Attend a comprehensive public school
- Study creative or humanities subjects
- Struggle during part of Year 12 and improve later
- Occasionally procrastinate
- Have a social life and extracurricular activities
- Feel uncertain about their ATAR until results day
They are usually not perfect. What they generally do well is respond to feedback.
When they receive a poor mark, they work out why. When they repeatedly run out of time, they complete timed papers. When their essays lack analysis, they seek feedback and rewrite them. When a study method produces no improvement, they change it.
The difference is often adaptability rather than intelligence.
How to Improve Your Chances of Reaching 90
Work Backwards From the Course, Not the Number
Find the university course you want to enter and check its previous selection rank, prerequisites and available adjustment factors.
Remember that an advertised selection rank is not always the same as the raw ATAR received by the lowest admitted student. Universities may apply adjustment points for factors such as subjects, location, educational disadvantage or extracurricular achievement.
Your goal might be a course with a selection rank of 90, but you may not need a raw 90 ATAR to receive an offer.
Prioritise Your Largest Mark Losses
Look at your recent assessments and determine where the easiest recoverable marks are.
Improving from 14 out of 20 to 17 out of 20 across repeated extended responses may be more valuable than spending ten hours perfecting a topic that contributes one multiple-choice question.
Your study plan should be based on evidence from your own work.
Use Feedback Immediately
Feedback has a short expiry date.
When you receive an assessment, review it while you still remember what you were thinking. Ask your teacher why marks were lost and complete another similar question within the same week.
Reading a teacher’s comment and promising to “remember it next time” is rarely enough.
Complete Timed Practice
Untimed study can make you feel prepared without testing whether you can perform under examination conditions.
Start with timed sections before moving into full papers. Mark them carefully and keep a record of recurring errors.
One properly reviewed paper is more useful than three papers completed without checking why you lost marks.
Do Not Make Panic-Based Subject Decisions
Do not drop a subject simply because someone online says it scales poorly. Do not continue a course you dislike solely because it scales well.
Consider your marks, ranking, workload, interest and the possibility that extra units may provide a useful backup. Scaling should be one consideration, not the entire decision.
Protect Your Ability to Keep Working
A 90 ATAR does not require you to abandon sleep, exercise or every social event.
Extreme schedules often feel productive for several days before becoming impossible to maintain. Consistent two-hour sessions across many weeks will usually achieve more than an occasional ten-hour panic session.
The goal is not to create the most impressive study timetable. It is to create one you will genuinely follow.
So, Is a 90 ATAR Hard?
A 90 ATAR is objectively a high result. It places you ahead of most students in your age group and requires strong overall performance.
But it is not reserved for naturally gifted students, selective-school duxes or people who have been preparing since Year 9.
You do not need perfect internal marks. You do not need a Band 6 in every subject. You do not need to study only Mathematics Extension and science courses. You do not need to feel confident throughout the entire year.
I certainly did not.
I spent much of Year 12 believing I was performing poorly because I focused on every weak result and compared myself with students aiming for ATARs far above mine. Receiving a 92 taught me that your perception of your performance can be much harsher than the final calculation.
The honest answer is this:
A 90 ATAR is difficult enough that you must take Year 12 seriously, but achievable enough that an ordinary, imperfect and occasionally stressed student can absolutely reach it.

Frequently Asked Questions
Is a 90 ATAR considered good?
Yes. An ATAR of 90 places you around the top 10% of your age cohort and can make you competitive for a wide range of university courses. However, whether it is the right target depends on the entry requirements for your preferred degree.
Can an average student get a 90 ATAR?
An academically average student can improve enough to achieve 90, but this usually requires them to perform above their previous level during Year 12. Consistent practice, useful feedback and better exam technique can produce substantial improvement.
Can you get a 90 ATAR without Band 6s?
It may be possible depending on your combination of HSC marks, subjects and the scaling applied that year. There is no rule requiring a particular number of Band 6 results. Your ATAR is calculated from scaled marks rather than a simple average of the HSC marks shown on your results page.
Can you get a 90 ATAR with low-scaling subjects?
Yes. Strong performance in lower-scaling subjects can still produce a high ATAR. Scaling should not be ignored, but selecting subjects in which you can perform well is generally more useful than choosing high-scaling courses you cannot manage.
How many hours should I study for a 90 ATAR?
There is no fixed number. The quality and consistency of your study matter more than the total time recorded. A student using focused practice and acting on feedback may progress faster than someone spending longer hours rereading notes.
Is it too late to aim for 90 after poor marks?
Not necessarily. The answer depends on how many assessments remain, their weightings, your current rankings and how much improvement is realistic. A weak early result makes the goal harder, but one assessment rarely determines your entire ATAR.
Is an ATAR calculator accurate?
ATAR calculators provide estimates based on historical scaling information. They are useful for testing possible scenarios, but scaling changes each year, so they cannot predict your exact result. UAC recommends treating its own ATAR Compass as a guide only.
