JEE Main 100 Days Plan 2027: A 14-Week Schedule

JEE Main 2027 Session 1 begins on 22 January 2027 in NTA's tentative exam calendar, exactly 100 days after Wednesday, 14 October 2026. The plan below rations those days instead of spreading them evenly across everything: four phases over 14 weeks, a mock count for each week, and separate hour budgets for Class 12 students who also face board exams and for droppers.

Last verified: 12 Oct 2026 against the National Testing Agency (NTA) exam calendar of 16 September 2026, NTA's JEE (Main) 2026 notices and information bulletin, and CBSE's 2026 date sheet circular.

Which date should your countdown run to?

Run it to 22 January 2027, the first exam day of Session 1. NTA's calendar, published on 16 September 2026, lists the session on 22–24 and 28–30 January 2027, with 31 January kept as a buffer day.

Three details shape everything below:

• The calendar is tentative. NTA says the dates are tentative and may change, and that detailed bulletins will follow separately. Before you book travel or ask school for leave, check NTA's site or our free JEE Main 2027 countdown, a Kalnehi Daily page that follows the official notices.
• Your own day comes later. For 2026, NTA said each candidate's centre, date and shift would be as shown on the admit card. Any of the six listed exam days could be yours, so plan as if the first one is.
• Session 2 isn't scheduled yet. The calendar only covers exams up to March 2027. In 2026 the bulletin scheduled the second session between 2 and 9 April, and for candidates who wrote both sessions, the final rank used the better of their two NTA scores. Treat Session 1 as a full attempt; April is a second chance, not the plan. Planning across both sessions is covered on the JEE Main preparation page.

What syllabus and paper pattern should the plan cover?

Prepare from NTA's syllabus for JEE (Main) 2026 and the 2026 Paper 1 pattern, because NTA hadn't published a 2027 information bulletin when we checked on 12 October 2026. If the 2027 bulletin changes the pattern, we'll update this plan.

Under the 2026 rules, Paper 1 (B.E./B.Tech.) was:

• a 3-hour computer-based test with 75 questions, 25 each in Physics, Chemistry and Mathematics;
• 20 multiple-choice questions (Section A) and 5 numerical-value questions (Section B) per subject, worth 100 marks per subject and 300 in all;
• marked +4 for a correct answer, −1 for a wrong one and 0 for a blank, in both sections;
• held in two shifts, 9:00 a.m. to 12:00 noon and 3:00 p.m. to 6:00 p.m.

The official unit list is on NTA's syllabus page; our chapter-wise JEE Main syllabus summary is built from it. Two units are easy to skip without noticing: Physics ends with Experimental Skills and Chemistry with Principles Related to Practical Chemistry. Keep both in your list.

How should you split the 100 days?

Split them into four phases of unequal length: about four weeks of chapter repairs, six of mixed revision, three of heavy mock practice and one light week. The boundaries (days 100–71, 70–29, 28–8 and 7–1) are our planning choice, set so each phase ends on a whole week.

Spend the first two days on an audit. Write one full paper under exam conditions, then mark every chapter in the NTA syllabus as done, weak or untouched. If you use Kalnehi Daily (our app), its syllabus tracker lets you mark each topic Not begun, Need revision or Completed, which maps onto those three labels; a notebook works just as well. The list decides what the repair weeks contain.

Our rule of thumb for the order: repair weak chapters before untouched ones, because a chapter you half know usually comes back in a few deep blocks. Take on an untouched chapter only if you can cover its basics inside the repair weeks and later chapters lean on it, such as vector algebra before 3D geometry, or the basic principles of organic chemistry before the reaction chapters. Otherwise park it, and in papers treat its questions as skip-unless-obvious rather than guesses.

From week 5, revision runs in three blocks that each touch all three subjects:

• Block A: mechanics, heat and thermodynamics; physical chemistry; algebra and trigonometry.
• Block B: electrostatics, current electricity, magnetism, electromagnetic induction and alternating current; organic chemistry; calculus.
• Block C: oscillations and waves, electromagnetic waves, optics, modern physics, electronic devices and experimental skills; inorganic and practical chemistry; coordinate geometry, vectors and 3D geometry, statistics and probability.

Added up, that is about 18–20 full papers for a Class 12 student and 21–23 for a dropper. If school pre-boards or practicals land in a mock-heavy week, cut that week to two papers rather than skipping the analysis.

How many hours a week does the plan assume?

We assume about 29 focused hours a week for a Class 12 student and about 46 for a dropper. These are planning assumptions, not official figures, so scale each row to the hours you actually log. Focused hours means time on JEE problems and notes, not coaching lectures, travel or school homework.

The arithmetic: a Class 12 student doing 3.5 hours on each of six school days plus 8 on Sunday gets 21 + 8 = 29. A dropper doing 7 hours on six days plus 4 on the seventh gets 42 + 4 = 46. We also assume each full mock costs about 5 hours: 3 to write it and roughly 2 to analyse it.

For Class 12 students, the boards are the other half of the picture. CBSE hasn't released its 2027 date sheet yet; its 2026 exams began on 17 February 2026. If 2027 follows a similar timeline, the boards come after Session 1 rather than during it, but your school's pre-boards and practicals may still fall inside these 100 days. Ask for those dates now and mark those weeks as lighter. The Class 12 boards and JEE balance guide covers how to share hours between the two. Droppers who are also fixing last year's habits should read the JEE dropper study plan alongside this one.

How should you rotate Physics, Chemistry and Maths within a day?

Touch all three subjects on most days, but give one subject the long, deep block and rotate which one gets it. A fixed order every day lets the weakest subject hide at the end of the evening.

Rotate the lead as Physics, Chemistry, Maths from Monday to Saturday, so each subject leads twice. For Class 12 students, Sunday is mock day; in repair weeks without a mock, use it for a second deep block on your weakest subject. Droppers should write papers on a 7-hour day and keep the 4-hour day light. In the mock-heavy weeks, a 3-hour paper plus its analysis won't fit a 3.5-hour school day, so Class 12 students should use Sundays and holidays, or write the paper one evening and analyse it the next.

How do you get marks back from mocks and an error log?

A mock pays off only through the analysis after it, so log every lost mark by its cause and redo those questions on a schedule. Under the 2026 marking, a wrong answer to a question you could have solved costs five marks compared with a right one: the four you missed plus the one deducted.

Give each error-log row the paper and question number, the chapter, the cause (concept gap, calculation slip, misread, ran out of time, unworked guess), a one-line fix and two redo dates, 3 and 7 days later. Concept gaps go into the next deep block for that subject. For slips, write down the exact step that broke, because the same step tends to break again. From week 13, start papers at 9:00 a.m. or 3:00 p.m., the 2026 shift times, so your sharpest hours line up with the real paper.

Worked example: what does one week look like for a Class 12 student?

A mixed-revision week is one mock with its analysis, plus subject hours weighted by what the error log found. Take a hypothetical Class 12 student in week 6 (20–26 November) on the 29-hour budget; the numbers are an illustration, not data from real students.

Their week 5 mock: 60 questions attempted, 40 right and 20 wrong, so the score is 40 × 4 − 20 × 1 = 160 − 20 = 140 out of 300. The error log sorts the 20 wrong answers into 8 concept gaps, 7 calculation slips or misreads, and 5 numerical-value answers typed in without working.

• Fixing the 7 slips is worth 7 × 5 = 35 marks, because each one turns −1 into +4.
• Leaving those 5 unworked numerical answers blank would have added 5 marks, each −1 becoming 0.
• Closing the 8 concept gaps is worth up to 40 marks, but it needs chapter time.

So week 6 starts with 5 hours for Sunday's mock and analysis, which leaves 24. Most concept gaps were in Physics, so Physics gets 10 hours (6 on Block B problem sets and 4 on the two chapters behind the gaps), Maths gets 8 and Chemistry 6. Each day ends with 30 minutes redoing the week's slips without looking at solutions, counted inside those subject hours. The hours follow the error log rather than the textbook order.

What should the last seven days look like?

No new topics: write one or two light papers early in the week at your shift's time, then switch to short notes, sleep and logistics. Stop full papers two days before your exam day.

• Download the exam-city slip and admit card as soon as NTA releases them. For both 2026 sessions, the bulletin scheduled admit card downloads 3–4 days before the exam date.
• Work out the route to your centre and the documents the admit card asks for.
• Wake at the same time each day, matched to your shift.
• Revise only from your own short notes and the error log.

What if you have fewer than 100 days left?

Join the table at the row that matches your days left, keep that row's mock count, and fold the missed repair work into your deep blocks. With 70 days left, start at week 5 and use each deep block on a weak chapter from the same revision block. With four weeks or fewer, start at week 11: mocks and the error log will find your weak chapters faster than a fresh audit would.
