So, you have 30 days left. Maybe a little more, maybe a little less.
First, take a deep breath. 30 days is not a lot of time, but it is enough to make a real difference in your score — if you use it wisely.
I have seen students improve by 15-20 marks in their final month just by following a structured revision plan. The key is not to panic and not to waste time on the wrong things.
This guide gives you a realistic, day-by-day Class 12 Maths revision plan for the next 30 days. It is not a fantasy schedule that assumes you will study 14 hours a day. It is practical, doable, and based on what actually works.
Let us get started.
First, a reality check: Where are you right now?
Before we dive into the plan, you need to honestly assess your current situation. The strategy changes depending on where you are starting from.
Situation A: You have completed NCERT and done some practice
Great! You are in a strong position. Your focus should be on revision, sample papers, and perfecting your weak areas. Follow the plan below as written.
Situation B: You have covered most chapters but not all
You need to prioritize. Focus on high-weightage chapters first (Calculus, Matrices, Vectors). For chapters you have not touched, at least read the NCERT examples and understand the basic concepts. You may not master everything, but you can still score well.
Situation C: You are seriously behind
Do not panic, but be realistic. Focus only on the most important chapters: Linear Programming (easy 5 marks), Probability (8 marks), Vectors + 3D Geometry (14 marks), and as much Calculus as you can manage. Skip the difficult conceptual chapters like Relations and Functions for now. Aim for 50-60 marks first, then build from there.
Important reminder:
This plan assumes you have at least seen most chapters once. If you are starting from zero with 30 days left, please also read our complete preparation guide for chapter prioritization.
30 days is enough to improve significantly, but it is not enough to learn everything from scratch. Be strategic.
Week 1 (Days 1-7): Calculus revision
Calculus is 35 marks – nearly half your paper. You need to start here.
| Day | Topic | What to Do |
|---|---|---|
| Day 1 | Continuity & Differentiability | Revise concepts, solve 10–15 NCERT problems. Focus on finding k values. |
| Day 2 | Continuity & Differentiability | Practice previous year questions on this topic. Check marking scheme. |
| Day 3 | Application of Derivatives | Revise maxima, minima, rate of change. Solve word problems carefully. |
| Day 4 | Application of Derivatives | More practice on application problems. Focus on understanding, not speed. |
| Day 5 | Integration | Revise all integration methods. Make a formula sheet if you have not already. |
| Day 6 | Integration + Definite Integrals | Practice definite integrals and properties. Solve at least 20 problems. |
| Day 7 | Differential Equations | Revise types of differential equations. Practice formation and solving. |
End of Week 1 goal: You should feel confident about Calculus. Not perfect, but comfortable. If you can solve 70-80% of Calculus problems correctly, you are on track.
Week 2 (Days 8-14): Algebra + Vectors + Probability
Now we cover the remaining high-weightage chapters.
| Day | Topic | What to Do |
|---|---|---|
| Day 8 | Matrices | Revise operations, types, transpose, symmetric matrices. Practice problems. |
| Day 9 | Determinants | Revise properties, cofactors, adjoint, inverse. Solve system of equations. |
| Day 10 | Vectors | Revise dot product, cross product, scalar triple product. Formula revision. |
| Day 11 | 3D Geometry | Lines and planes in 3D. Distance formulas. Angle between lines/planes. |
| Day 12 | 3D Geometry | Continue practice. Focus on shortest distance and coplanarity problems. |
| Day 13 | Probability | Conditional probability, Bayes theorem. Draw tree diagrams for every problem. |
| Day 14 | Probability + Linear Programming | Probability distributions. Linear Programming graphical method (easy 5 marks). |
End of Week 2 goal: All major chapters revised. You should now have touched every important topic at least once in these 14 days.
Week 3 (Days 15-21): Sample paper practice
This is the most important week. You need to practice full papers in exam conditions.
| Day | Activity | Details |
|---|---|---|
| Day 15 | Sample Paper 1 | Solve CBSE official sample paper 2026. Full 3 hours. No breaks. |
| Day 16 | Analysis + Weak areas | Check answers. Note mistakes. Revise weak topics from the paper. |
| Day 17 | Sample Paper 2 | Previous year board paper (2025). Time yourself strictly. |
| Day 18 | Analysis + Weak areas | Check answers. Focus on recurring mistakes. Practice those topics. |
| Day 19 | Sample Paper 3 | Previous year board paper (2024). Simulate real exam conditions. |
| Day 20 | Analysis + Weak areas | Check answers. By now you should see patterns in your mistakes. |
| Day 21 | Relations & Functions + Application of Integrals | Quick revision of these remaining chapters. Solve key NCERT problems. |
How to analyze your sample papers:
- Check each answer against the marking scheme (not just final answer, but steps too)
- Calculate your score honestly – do not give yourself extra marks
- List the topics where you lost marks
- Identify if mistakes were conceptual (did not understand) or silly (calculation error)
- Spend extra time on conceptual mistakes – those need revision
End of Week 3 goal: You should be scoring 60+ marks in your practice papers consistently. You know your weak areas and have worked on them.
Week 4 (Days 22-30): Final revision and rest
This is the home stretch. The goal now is to consolidate, not to learn new things.
| Day | Activity | Details |
|---|---|---|
| Day 22 | Sample Paper 4 | One more full paper. Check your improvement from Week 3. |
| Day 23 | Formula revision | Go through your entire formula sheet. Twice. Make sure everything is solid. |
| Day 24 | Weak chapter focus | Spend the day on your weakest chapter. Just that one chapter. |
| Day 25 | Sample Paper 5 | Final full paper. This is your dress rehearsal. |
| Day 26 | Light revision | Review your notes. Skim through NCERT examples. No heavy practice. |
| Day 27 | Light revision | Continue light revision. Focus on formulas and concepts, not problems. |
| Day 28 | Very light revision | Just formula sheet. Maybe some easy problems for confidence. Relax. |
| Day 29 | Rest day | Light reading only. Pack your bag. Sleep early. Do not study hard. |
| Day 30 | EXAM DAY | Stay calm. Trust your preparation. You have done the work. Now show it. |
Ideal daily schedule for these 30 days
Here is a realistic daily schedule. Adjust based on your school timings and other subjects.
| Time | Activity |
|---|---|
| 6:00 – 6:30 AM | Wake up, freshen up |
| 6:30 – 7:00 AM | Formula revision (fresh mind absorbs better) |
| 7:00 – 7:30 AM | Breakfast |
| 7:30 – 10:30 AM | Study session 1: Main topic of the day (3 hours focused) |
| 10:30 – 11:00 AM | Break – walk, snack, rest your eyes |
| 11:00 AM – 1:00 PM | Study session 2: Problem practice (2 hours) |
| 1:00 – 2:30 PM | Lunch + rest (do not skip this!) |
| 2:30 – 5:00 PM | Study session 3: Continue practice or revise another subject |
| 5:00 – 6:00 PM | Break – exercise, walk, relax |
| 6:00 – 8:00 PM | Study session 4: Review + solve doubts from the day |
| 8:00 – 9:00 PM | Dinner + family time |
| 9:00 – 10:00 PM | Light revision or other subject |
| 10:00 PM | Sleep (non-negotiable – tired brain cannot perform) |
This gives you about 8-9 hours of study time per day. That is plenty if you use it well. Quality over quantity, always.
Critical tips for the last 30 days:
- Do NOT learn anything new in the last 5 days. Only revise what you already know.
- Sleep is not optional. A tired brain makes silly mistakes that cost you marks.
- If you feel overwhelmed, focus on high-weightage chapters only. You cannot do everything.
- Keep your phone away during study hours. Every distraction costs you 20+ minutes of focus.
- Eat properly. Your brain needs fuel. Skipping meals to study more is counterproductive.
Frequently asked questions
What if I have not finished the syllabus yet?
Focus on high-weightage chapters: Calculus (35 marks), Vectors + 3D (14 marks), Matrices + Determinants (10 marks), Probability (8 marks), and Linear Programming (5 marks). These add up to 72 marks. Master these first, then cover what you can from the rest.
How many sample papers should I solve in these 30 days?
Aim for 5-7 full papers solved in exam conditions. Quality is more important than quantity. After each paper, spend time analyzing your mistakes – that is where real improvement happens.
Should I study on the day before the exam?
Only light revision. Go through your formula sheet once. Do not solve difficult problems or try to learn new concepts. Your brain needs rest to perform well tomorrow. Pack your bag, eat well, and sleep by 10 PM.
What if I am scoring low in practice papers?
Do not panic. Analyze where you are losing marks. Is it calculation errors? Revise more carefully. Is it conceptual gaps? Focus on those specific topics. Is it time management? Practice attempting papers faster. Low scores in practice are okay – that is why you practice, to improve.
Can I really improve in just 30 days?
Yes. I have seen students improve by 15-20 marks in the final month. The key is focused effort. Do not waste time on social media or random YouTube videos. Follow the plan, practice daily, analyze your mistakes, and you will see improvement.
What topics should I skip if I do not have enough time?
If you are very short on time, Relations and Functions (8 marks) can be kept for last as it is conceptually tricky. But never skip Linear Programming (easy 5 marks) or Probability (8 marks) – these are scoring chapters that can be learned quickly.
Quick summary of the 30-day plan
- Week 1 (Days 1-7): Complete Calculus revision – this is 35 marks
- Week 2 (Days 8-14): Revise Matrices, Vectors, 3D Geometry, Probability, Linear Programming
- Week 3 (Days 15-21): Solve sample papers, analyze mistakes, work on weak areas
- Week 4 (Days 22-30): Final revision, light practice, rest before exam
Remember: The last week should be about consolidation and rest, not cramming. Trust the work you have done.
A final word from me:
I know these 30 days feel intense. There is pressure from everywhere — parents, teachers, your own expectations.
But here is what I want you to remember: This is just one exam. It is important, yes. But it does not define who you are or what you can achieve in life.
Do your best. Follow the plan. Stay calm. And whatever happens, know that you gave it your honest effort.
You have got this.
