How to actually use your 90 days

Full coverage, one real revision cycle, and a weekly mock series — the standard serious-attempt window.

Approach
one full pass, one structured revision cycle, and a weekly mock series

This 3-month plan gives you 90 days to work through 23 weighted NDA topics across 2 subjects — roughly 0.26 new topics a day at 3.5–4.5 hours of focused study. That is a sustainable pace that leaves real room for revision instead of just first-time coverage.

NDA marks are not spread evenly across subjects. Mathematics and GAT carry the heaviest weightage in recent papers, so this plan front-loads them — so they anchor the first pass and earn the most revision time later. Cover the entire syllabus once, then let weightage decide what earns a second and third pass. Nothing is skipped — only deprioritised.

90 days is enough to cover all 23 NDA topics once, revise them once more, and build a genuine mock-test habit on top. The risk is plateauing after the first pass. Block out the revision cycle in your calendar now, before mocks crowd it out.

What to prioritise & cut

Cover the entire syllabus once, then let weightage decide what earns a second and third pass. Nothing is skipped — only deprioritised.

Mock tests & revision

Topic-wise tests while you learn, then weekly full-length mocks once the first pass is done. Track sectional timing, not just the total.

Weekly rhythm

Roughly the first 60% of the timeline on the first pass, the next 25% on weight-prioritised revision, the last 15% on full mocks and an error-log review.

NDA 3-Month Plan — common questions

Is 90 days enough to prepare for NDA? +

90 days is enough to cover all 23 NDA topics once, revise them once more, and build a genuine mock-test habit on top. The honest answer depends on your starting point, but this 3-month plan is built to get the most from the time you have: full coverage, one real revision cycle, and a weekly mock series — the standard serious-attempt window.

How many hours a day does this NDA 3-month plan need? +

Plan for 3.5–4.5 hours of focused study, covering about 0.26 new topics a day. Roughly the first 60% of the timeline on the first pass, the next 25% on weight-prioritised revision, the last 15% on full mocks and an error-log review.

What should I skip if I am short on time? +

Cover the entire syllabus once, then let weightage decide what earns a second and third pass. Nothing is skipped — only deprioritised.

When should I start mock tests on this plan? +

Topic-wise tests while you learn, then weekly full-length mocks once the first pass is done. Track sectional timing, not just the total.
