Last 30 Days Revision Plan for CBSE Class 12 Board Exam

Last 30 days is not for learning new topics. It is for consolidation, error correction and mock discipline. Here is a plan built from what actually works.

Guiding principles

• Don't study more subjects than you have time for. 4 hours on one chapter beats 30 minutes each on four.
• Sleep 7 hours minimum. No exception. Sleep-deprived brain forgets formulas the next morning.
• Mock every 4 days. Solving matters more than reading.

Week 1 (Days 1–7): Formula sweep

Goal: revise ALL formulas of ALL chapters. Not deep — just refresh.

| Day | Morning (2h) | Afternoon (2h) | Evening (1h) | |-----|--------------|----------------|--------------| | 1 | Physics — Ch 1, 2 | Chemistry — Ch 1, 2 | Maths — Ch 1 | | 2 | Physics — Ch 3, 4 | Chemistry — Ch 3, 4 | Maths — Ch 2 | | 3 | Physics — Ch 5, 6 | Chemistry — Ch 5, 6 | Maths — Ch 3 | | 4 | Full-length physics paper (3h) | Review answers | Rest | | 5 | Physics — Ch 7, 8 | Chemistry — Ch 7, 8 | Maths — Ch 4 | | 6 | Physics — Ch 9, 10 | Chemistry — Ch 9, 10 | Maths — Ch 5 | | 7 | Full-length chemistry paper (3h) | Review | Rest |

Week 2 (Days 8–14): Deep dive on weak chapters

Identify from Week 1 mocks where you lose marks. Common weak areas:

• Physics: EMI (electromagnetic induction), Wave optics interference
• Chemistry: Electrochemistry, Chemical kinetics numerical
• Maths: Integration by parts, Vectors 3D
• Biology: Genetics dihybrid ratio, Molecular basis DNA replication

Spend 4h/day on your weakest 2 chapters. Redo every worked example. Attempt HOTS practice questions.

Week 3 (Days 15–21): Full mock discipline

One full mock every alternate day. Analyse mistakes the same day — don't stack mocks.

Mock schedule:

• Day 15: Physics (Set A)
• Day 17: Chemistry (Set A)
• Day 19: Maths (Set A)
• Day 21: Biology (Set A)

Between mocks: revise ONLY the specific chapters where you dropped marks.

Week 4 (Days 22–30): Sharpen + confidence

• Day 22–24: revise formulas + common mistakes for every chapter.
• Day 25–27: one final mock per subject.
• Day 28: rest morning, revision evening.
• Day 29: revise Physics + Chemistry short notes only. Sleep by 10 PM.
• Day 30 (exam day): light revision of tricky formulas, no new material.

What NOT to do

• Do not start reference books (HC Verma, RD Sharma) in the last 30 days if you haven't already.
• Do not attempt topics you skipped all year — you cannot master a new chapter in 3 days.
• Do not compare notes with friends the night before an exam. It creates panic.
• Do not skip breakfast on exam day. Blood sugar affects recall.

Board Formulas workflow

For each chapter you revise:

1. Read the formula section — click "Why this formula?" for derivations you forgot.
2. Read Common Mistakes — those are the marks you are most likely to lose.
3. Attempt Practice questions — hide the answer first.
4. Note the ones you got wrong. Redo them 2 days later.

Discipline over intensity. Every day.
