Summary: Write January as a full, serious attempt. Use the week after it to analyse, protect your board exam time in February and March, and keep Physics, Chemistry and Mathematics alive with short daily JEE practice. Spend the last ten days before April on full mocks and your error notebook.How the two sessions work
NTA holds JEE Main Paper 1 in two sessions. In the 2026 cycle, Session 1 was scheduled for 21 to 30 January and Session 2 for 2 to 9 April, with Session 1 scores declared in mid-February. You can write one or both. If you write both, the better of your two total NTA scores is used for your rank, and it is the total that counts, not the best subject from each attempt. Check the dates in the bulletin for your year, since they shift a little every cycle.
For Maharashtra students, the difficulty is obvious from the calendar. The State Board HSC exams usually begin in February and run into March, and CBSE and ISC exams fall in the same stretch. The ten weeks between the two sessions are also your board exam season.
Treat January as the real exam
Some students tell us they will "just see the paper" in January and prepare properly for April. In our experience this rarely works. The ones who write January casually tend to repeat the same mistakes in April, because they never learnt what the real exam pressure did to them.
Go into January with the full syllabus revised once, at least ten full mocks behind you, and a clear plan for the order in which you will attempt the subjects. If you do well, April becomes a chance to improve with less pressure. If you do badly, you will at least have clean information about what went wrong.
The week after January
Do not jump straight into board revision the day after your paper, and do not spend a week refreshing answer key websites either. Take one day off. Then spend two or three days on these jobs:
- When NTA releases the recorded responses and provisional key, check your actual marks subject by subject.
- Write down, from memory, which questions you left and why: did not know the concept, knew it but ran out of time, or panicked.
- Count your wrong answers and sort them into careless errors and concept errors.
- Compare the time you spent on each subject with your plan.
That page of notes decides your April plan. The table below turns it into decisions.
| What your January analysis shows | What to do before April |
|---|---|
| Many careless errors (sign mistakes, misread questions) | Fewer new questions, more timed sectional tests with a strict re-check routine. Keep a list of your repeated mistakes and read it before every mock. |
| Ran out of time in one subject | Practise that subject in 60-minute timed blocks. Decide in advance the maximum time you allow per question before moving on. |
| Whole chapters left blank | Pick two or three high-return chapters and finish them properly. Do not try to cover every gap in ten weeks. |
| Score close to what you wanted | Consolidate. Board exams first, light daily JEE practice, full mocks in the last fortnight. |
| Planning to write JEE Advanced | Keep up a steady amount of Advanced-level problem solving through February and March, since Advanced follows soon after April. |
February and March: boards and JEE together
Your board syllabus and the JEE Main syllabus overlap heavily in Physics, Chemistry and Mathematics. Board revision is not lost time for JEE. Writing out derivations, reading NCERT Chemistry line by line and practising integration for the board paper all feed directly into April.
What you must protect is speed with objective questions. Students who stop solving MCQs for six weeks find their accuracy has dropped when they come back. Keep a small daily JEE block, even on board exam days.
A week-by-week outline
Adjust the weeks to your own board timetable.
| Period | Main focus | Daily JEE practice |
|---|---|---|
| First week after January | Analysis, rest, board practical preparation | Rework every question you got wrong in January |
| Weeks 2 to 3 | Board revision, especially language and non-JEE subjects | 25 to 30 mixed MCQs a day, timed |
| Board exam weeks | The board paper in front of you | 15 to 20 MCQs on days without a paper, from the subject you wrote last |
| After boards end | Weak chapters from your January analysis | One sectional test a day, alternating subjects |
| Last 10 days | Full-length mocks at the same time as your likely shift | Mock, analysis, error notebook. Nothing new. |

A few things that go wrong in April
Students who did well in January sometimes relax too much and write April without having solved a timed paper for a month. The better of the two scores counts, so a weak April does not hurt your rank, but it wastes a chance to improve it.
Students who did badly in January sometimes do the opposite and drop their boards to cram JEE. This is risky. Admission to NITs and IITs also needs the Class 12 requirement (75% aggregate, or 65% for SC and ST, or the top 20 percentile of your board), and your board marks stay with you.
Finally, remember that April also decides who qualifies for JEE Advanced. If you are aiming for an IIT, April is your last chance to get into the top candidates who can register for Advanced, and it is also only a few weeks before the Advanced paper itself.
Common questions
Is it compulsory to write both sessions?
No. You can write only one. Most students write both, because the better score counts and a second attempt costs nothing in rank terms.
Is the April paper harder than January?
Every shift has a different paper and difficulty varies. Percentiles are calculated within each shift, which evens out the difference. Do not choose a session hoping for an easier paper.
Can I skip January and prepare only for April?
You can, but you lose a free attempt and the experience of the real exam. We advise almost every student to write January seriously.
