How to Prepare for Class 10 Maths Board Exam and Score 90+
Let's be honest — the Class 10 Maths board exam scares a lot of students.
Not because it's impossibly hard. But because nobody really tells you exactly what to do, when to do it, and how to stop panicking when you open a question paper and your mind goes blank.
That's what this guide is for. This is a complete, step-by-step breakdown of class 10 maths board exam preparation — the kind your teachers might not have time to give you individually. We're covering the exam pattern, which chapters matter most, a realistic 8-week study plan, exam-day strategy, and everything in between.
And here's the good news: Maths is the most scoring subject in Class 10. Every step you write earns marks. You don't have to be a "Maths person" to score 90+. You just have to prepare smart.
First — Understand What the Exam Actually Tests
Before you open a single textbook, understand what CBSE is actually asking of you.
The Class 10 Maths board exam is 80 marks (written) plus 20 marks for internal assessment — practicals, notebooks, periodic tests. The written paper has four types of questions:
- 1 Multiple Choice Questions (MCQs) — don't skip these, they're free marks if you've practised
- 2 Short Answer Type I (SA-I)
- 3 Short Answer Type II (SA-II)
- 5 Long Answer (LA) — these need clear step-by-step working
One thing most students don't realise: CBSE awards marks for every correct step, not just the final answer. So even if you make a silly calculation mistake at the last line, you still get 3 or 4 out of 5 marks for writing the correct method. That's huge. That's the difference between a 72 and an 85.
Also — CBSE has been adding more case-based and application questions in recent years. Mugging up formulas isn't enough anymore. You need to understand when and why to use them.
Chapter-Wise Marks Weightage — Know Where to Focus
Not all chapters are equal. Here's the marks distribution you need to plan your class 10 maths board exam preparation around:
Look at that. Algebra alone is 20 marks. Algebra + Geometry + Trigonometry = 47 marks out of 80.
So where should most of your early preparation time go? Those three units. Master them first, then give time to the rest.
The 8-Week Class 10 Maths Board Exam Preparation Plan
Here's a realistic chapter-wise plan. Adjust the timeline based on how many weeks you have left — if you're starting late, compress it, but don't skip chapters entirely.
Weeks 1–2: Algebra 20 marks
Start here. Algebra carries the most marks and also takes the most practice time.
- Polynomials: understand what zeroes mean, learn the relationship between zeroes and coefficients
- Pair of Linear Equations: graphical method, substitution, elimination — practise all three
- Quadratic Equations: factorisation, completing the square, quadratic formula, discriminant
- Arithmetic Progressions: nth term formula, sum of n terms, word problems (these come every year)
Target: solve at least 3 Quadratic Equations problems and 2 AP problems every single day of these two weeks. That's 42 problems minimum — and you'll feel the difference.
Weeks 3–4: Geometry and Coordinate Geometry 23 marks
Geometry is where students either love it or leave marks on the table. The trick is to understand the theorems — not just memorise them.
- Triangles: AA, SAS, SSS similarity criteria — practice drawing diagrams first, then write the proof
- Circles: tangents from an external point, chord theorems — these are 3–5 mark questions almost every year
- Coordinate Geometry: distance formula, section formula, area of triangle with coordinates
For geometry, always draw a neat diagram before you start solving. Examiners notice neat diagrams — and they help you think clearer too.
Weeks 5–6: Trigonometry and Mensuration 21 marks
Trigonometry sounds scary. It isn't — once you know the standard angle values and the key identities, most questions follow a pattern.
- Memorise sin, cos, tan values for 0°, 30°, 45°, 60°, 90° — these come up constantly
- Trigonometric identities: sin²θ + cos²θ = 1 (and its variations) — practise proving different identities
- Heights and Distances: draw the diagram first, label angles of elevation/depression, then solve
- Mensuration: areas of sectors and segments, surface area and volume of combination shapes
Heights and Distances has shown up in the CBSE Class 10 Maths board exam every single year. That's 4–5 marks you can practically guarantee if you've done 10–12 practice problems.
Week 7: Statistics, Probability, and Number Systems 16 marks
Don't leave these for last and then rush. They're actually quite manageable with focused effort.
- Statistics: mean (direct method, assumed mean method, step-deviation method), median, mode — know all three
- Probability: classical probability definition, complementary events, simple word problems
- Real Numbers: Euclid's division lemma, HCF and LCM using prime factorisation, proving irrationality
Probability questions in Class 10 are usually 2 marks and quite direct. Don't overthink them. They're some of the easiest marks in the paper.
Week 8: Full Revision + Mock Exams
This week is not for learning anything new. It's for consolidating what you've already studied.
- Solve one full 80-mark paper every 2 days under timed, exam-like conditions (no phone, no breaks)
- After each paper, mark it yourself and write down every question where you lost marks
- Go back to those chapters and revise specifically the weak spots
- Review your formula notebook every morning for 15 minutes
- Don't start any new reference book in this week
How to Build a Formula Notebook That Actually Works
This is something every topper does, but most students skip. Don't skip it.
Get one A5 notebook just for formulas. Every time you study a new chapter, write the key formulas, identities, and theorems on one page. That's it. Keep it short.
What to include:
- All trigonometric identities (sin²θ + cos²θ = 1, 1 + tan²θ = sec²θ, etc.)
- Quadratic formula and when to use discriminant for nature of roots
- AP formulas: aₙ = a + (n−1)d and Sₙ = n/2 [2a + (n−1)d]
- Area and volume formulas for cone, cylinder, sphere, frustum
- Distance formula, section formula, midpoint formula
- Euclid's lemma, HCF×LCM relationship
Read this notebook every morning before you start studying. By exam week, these formulas should feel as natural as your own name.
Solving Previous Year Papers — The Single Best Thing You Can Do
You've probably heard this before. But do you actually know why it works so well?
CBSE repeats question patterns. Not exact questions, but the same type of problem from the same chapters with slightly different numbers. When you've solved 6–8 years of papers, you start recognising patterns — and in the exam, familiar patterns feel like old friends.
Here's how to actually use previous year papers:
- Set a timer for 3 hours. No phone, no pausing
- Attempt the full paper as if it's the real exam
- After finishing, check with the answer key and mark yourself honestly
- For every question you got wrong, write down why — wrong formula? Calculation mistake? Didn't know the method?
- Revisit those specific topics before the next paper
Aim for at least 6–8 full papers before your board exam. The last 5 years of CBSE Class 10 Maths papers are freely available on the CBSE official website.
Exam Day Strategy — How to Attempt the Paper for Maximum Marks
You know the content. Now here's how to get full marks from what you know.
Use the 15-Minute Reading Time — Don't Just Sit There
CBSE gives you 15 minutes to read the question paper before you write a single word. Most students waste this time. Don't.
During those 15 minutes: scan the entire paper, put a small tick next to questions you're confident about, and plan which sections you'll tackle first. Walk into the writing time with a mental map of the paper.
Start with Questions You Know
Attempt your most confident questions first. This builds momentum, secures marks early, and — honestly — calms your nerves. Nothing settles exam anxiety faster than filling up answer pages.
Write Every Step. Every. Single. One.
Even if a step feels obvious. Even if you think the examiner will "get it". Write it.
Before solving: write the formula you're using. During solving: show each calculation. At the end: write the answer with the unit (cm, m², etc.). That's how you get full step marks — and how you protect yourself from losing marks due to a single arithmetic error.
Time Allocation
Roughly 1 minute per mark is the benchmark. A 5-mark question should take 5–7 minutes maximum. If a question is eating up 12 minutes and you're still stuck, leave it and come back. Don't let one question cost you three others.
Last 30 Days Before the Exam — What to Do (and What Not To)
The final month is not the time to panic-study everything from scratch. Here's what actually works:
- Revise formula notebook every morning — 15 minutes, no exceptions
- Solve 1 full-length paper every 3–4 days
- Spend extra revision time on your 2–3 weakest chapters specifically
- Eat well, sleep 7–8 hours — this isn't optional, it directly affects how your brain performs
- On the last 2 days before the exam: light revision only, no new topics
And the night before? Go through your formula notebook one last time, pack your stationery and admit card, and sleep. That's it. Your preparation is already done by then — trust it.
Frequently Asked Questions
Section D · Very Short Answer — tap a question to reveal the model answer
Two to three focused hours is enough for most students. But here's the thing — quality beats quantity every time. Thirty minutes of concentrated problem-solving is worth more than two hours of half-distracted reading. Don't count hours; count problems solved.
Yes, NCERT is your most important resource and is enough to score 80–85 marks. For 90+, solve NCERT Exemplar problems and 5–6 years of previous year papers after completing the textbook. Don't jump to other reference books before finishing NCERT completely.
Algebra carries 20 marks, Geometry 15, and Trigonometry 12. That's 47 marks out of 80 from just three units. Get these right and you're already more than halfway to 90+.
The honest answer? Practice under timed conditions, every day. Silly mistakes come from rushing. When you've solved 200+ questions under time pressure, your brain slows down naturally and checks its own work. Also — always write the formula before you use it. That one habit alone prevents a surprising number of errors.
Yes. 100%. Maths improves with practice, not talent. Students who score 90+ aren't naturally gifted — they've just solved more problems than everyone else. Start where you are, follow the plan in this guide, clear doubts the same day they appear, and 90+ is absolutely within reach.
Light revision only. Go through your formula notebook and maybe revisit the 2–3 chapters where you feel least confident. Don't start any new topic. Pack your admit card, pens, pencils, eraser, compass, and ruler the night before. Then sleep early. Seriously — sleep is not wasted time before an exam. It's the most important preparation you can do.
Ready to Score That 90+?
Here's the summary of everything that works:
- Start with NCERT — complete every exercise before opening any other book
- Build and review a formula notebook daily
- Follow the chapter-wise priority: Algebra → Geometry → Trigonometry → the rest
- Solve 6–8 full previous year papers under real exam conditions
- On exam day: use reading time, start confident, write every step, manage time
Class 10 Maths board exam preparation isn't about being smart. It's about showing up, doing the work, and knowing exactly what to do when you sit down in that exam hall. You have everything you need.
