Summary: For most students, Biology first, then Chemistry, then Physics works best: fast, confident marks early and the most time left for the slowest section. Budget about 45 to 50 minutes for Biology, 35 to 40 for Chemistry and 55 to 60 for Physics, keep 15 to 20 minutes spare, and attempt every section in two rounds. Test the plan in at least ten full mocks before the exam.The numbers you are working with
In the 2026 bulletin, NEET UG had 180 compulsory questions (45 Physics, 45 Chemistry and 90 Biology) and a duration of 180 minutes, with +4 for a correct answer and minus 1 for a wrong one. The June 2026 re-exam was given 3 hours 15 minutes to cover extra verification in the hall, so read your admit card for the exact timing in your year. This post assumes 180 minutes of working time.
One minute per question sounds tight, but the questions are not equal. A direct NCERT Biology question can take 20 seconds; a two-step Physics numerical can take three minutes. The whole plan rests on spending less than a minute where you can, to buy time where you must.
Which order to attempt
There is no single correct order, but there are good reasons behind the common one.
| Order | Suits | Risk |
|---|---|---|
| Biology, Chemistry, Physics | Most students; anyone whose Biology is their strongest subject | Physics gets the tired end of the paper |
| Chemistry, Biology, Physics | Students who warm up better with a mix of recall and short calculation | Long Chemistry numericals can eat into Biology time |
| Physics, Chemistry, Biology | Students strong in Physics who want to tackle it with a fresh mind | A bad start in Physics can shake confidence for the rest of the paper |
We suggest Biology first for most students. Biology is half the paper, it is the section where you can answer fastest, and finishing 90 questions early leaves you calm and with plenty of time for Physics. It also makes sense for the tie-break, since NTA breaks ties first on Biology marks.
Whatever order you choose, fix it by December and use it in every mock. Changing the order on exam day is one of the most common ways students lose time.
A time budget
| Section | Questions | Target time | Clock (if starting at 0:00) |
|---|---|---|---|
| Biology (Botany and Zoology) | 90 | 45 to 50 minutes | 0:00 to about 0:50 |
| Chemistry | 45 | 35 to 40 minutes | about 0:50 to 1:30 |
| Physics | 45 | 55 to 60 minutes | about 1:30 to 2:30 |
| Second look and OMR check | 15 to 20 minutes | 2:30 to 2:50 | |
| Final buffer | About 10 minutes | 2:50 to 3:00 |
Write the three checkpoint times (for example 2:50, 3:30 and 4:30 if the paper starts at 2:00) on the rough area of your booklet as soon as you are allowed to write. At each checkpoint, move on even if a section is unfinished. You can return in the second look.
Two rounds inside each section
Do not try to solve every question in the order it is printed. Within each section:
- Round one: Go through every question. Answer those you are sure of at once. If a question will clearly take longer than two minutes, or you are unsure between options, mark it in the booklet with a symbol and move on.
- Round two: Return to the marked questions. Solve the ones that need time, and decide on the ones where you were unsure.
Use two different marks in the booklet in round one: one for "I can solve this, but it is long", another for "I am unsure between options". The first type is almost always worth returning to. The second type needs the rules in our post on when a guess is worth it in NEET.
If a Physics question makes you stuck for more than two minutes in round one, you have already spent the time of two average questions. Leave it. It will be there in round two.
OMR habits that protect marks
As long as NEET is a pen-and-paper exam, the OMR sheet is part of the exam. A few habits save students every year from losing marks they had earned:
- Mark the OMR in blocks, for example after every page or every 10 to 15 questions, rather than all at the end. Leaving the whole sheet for the last 15 minutes is dangerous.
- Each time you bubble a block, check that the question number in the booklet matches the row on the OMR. One skipped row shifts every answer after it.
- Darken the bubble fully with the pen provided. A mark cannot be changed once made, so bubble only final answers.
- Keep the doubtful questions off the OMR until you decide in round two.
If NEET moves to a computer-based format, as the government has said is under consideration for 2027, the OMR habits will not apply, but the two-round method and the time budget will. Practise on whichever format your year's bulletin confirms.
Practise the plan, then adjust it
A time plan only works if it has been tested. Take full mocks at the same time of day as the real exam, in one sitting, with a printed OMR sheet. After each mock, write down:
- The actual time you finished each section
- How many questions you left for round two, and how many of those you then solved correctly
- Any OMR errors
- The section where you lost the most marks, and why (concept, calculation, reading or time)
After five mocks, adjust your budget. If Biology regularly takes 55 minutes, either speed up your NCERT recall or give Physics a little less. After ten mocks, the plan should feel automatic. Our previous year papers section lets you attempt past NEET papers online with a rank and analysis, which is good for this kind of practice.
On the day
Spend the first minute after the booklet opens checking that it is complete and correctly printed, and writing your checkpoint times. Then start with your planned section even if a question from another section catches your eye. If a section feels unusually hard, remember that it is hard for everyone and percentile is relative. Stick to the checkpoints, and trust the plan you have practised.
Common questions
Which subject should I attempt first in NEET?
Most students do best starting with Biology, because it is fast and builds confidence, then Chemistry, then Physics. Choose the order that works in your mocks and keep it fixed.
How much time should I give Physics in NEET?
About 55 to 60 minutes for 45 questions is a sensible target for most students. Save time in Biology to make this possible.
Should I fill the OMR sheet at the end?
No. Fill it in blocks as you go, checking question numbers each time. Leaving it all for the end risks running out of time or shifting answers by one row.
