How to Score Good Marks in Maths

Maths is the one subject where your rank and your marks are both decided by process — how you practise, how you write working, and how you protect marks under pressure. This is the exact method our tutors use with students who plateaued at 60 and reached 90s.

How do you score good marks in Maths in one line?

Finish and re-finish NCERT solved examples and exercises, then do these four things every week: write every step, practise daily, recheck your personal error list, and protect easy marks first in the exam.

Why maths scores plateau (and the fix)

Students who plateau at 60–70 rarely have a 'difficulty' problem — they have a coverage problem. In CBSE boards and foundation exams, the majority of marks come from NCERT-pattern questions. The student stuck at 70 has usually: read the chapter, understood it in class, and never revisited it again.

  • Solve NCERT solved examples on paper, not in the head — 'I get it' is not the same as 'I can reproduce it'.
  • Complete the back exercises in full. Board questions are reworded versions of these.
  • Re-solve every question you got wrong a second time 10 days later.

The 3-pass rule

Pass 1: learn it in class. Pass 2: solve all NCERT examples at home. Pass 3 (before exams): re-solve only the ones you marked wrong. Three passes take less total time than a desperate pre-exam all-nighter.

Master the fundamentals that carry the marks

Every high-weightage topic in Class 10–12 collapses into a handful of formulas. Master them cold — you should be able to recall and apply them without thinking. For example, the workhorse of algebra:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
Quadratic formula — Class 10 Algebra

Weightage below is the CBSE reality — prioritise in this order:

  1. Class 10: Number Systems & Algebra (incl. Quadratic Equations, Arithmetic Progressions) and Geometry together carry the largest share of the 80-mark paper.
  2. Class 12: Calculus (Continuity, Differentiation, Application of Derivatives, Integrals, Differential Equations) is the single biggest block — roughly a third of the paper.
  3. Vectors & 3D, Linear Programming and Probability are the 'quick full-marks' topics — high weightage for low effort.
  4. Class 11: Sets/Relations, Trigonometry and Straight Lines form the base of everything above; a weak Class 11 base quietly caps your Class 12 score.

Build the step-by-step solving habit

Board examiners award steps, not just final answers. A correct method with a wrong final arithmetic still earns most of the marks — but only if the steps are written. This one habit is worth 5–8 marks in almost every paper. Here is the format we make our students use:

  1. Write 'Given' — restate the data in one line.
  2. Write the formula or approach you will use.
  3. Show each calculation step, numbered if it helps.
  4. Box the final answer, and always add the unit.

Marks are given to the method

If you leave your final answer blank but your steps are clean, you still collect method marks. Students who 'do it in the head' and write only the answer get exactly one mark for a fully correct 5-mark question if a slip crept in.

Sports-style practice plan

Weekly maths practice schedule (boards year)

DaySessionFocus
Mon–Thu45–60 minOne chapter's examples + 10 questions; note all errors
Fri60 minRe-solve 10 questions from earlier this week you missed
Sat90 minFull chapter test or 1-hour timed set (board marks pattern)
Sun30 minFormula sheet revision + error-list scan

Timed sets beat unscheduled study

Once a week, do a timed set at board-pattern marks. It trains speed, stamina and the biggest exam killer: finishing the easy questions slowly and running out of time on the ones you could have solved.

A worked example, step by step

Here is the exact presentation that gets top marks. Solve for x in x25x+6=0x^2 - 5x + 6 = 0:

  1. Given: a = 1, b = –5, c = 6.
  2. Formula: apply the quadratic formula (shown above): x = (−b ± √(b² − 4ac)) / 2a.
  3. Discriminant: b² − 4ac = 25 − 24 = 1, so √(b² − 4ac) = 1.
  4. Roots: x = (5 ± 1) / 2 → x = 3 or x = 2.
  5. Answer boxed: x = {3, 2}. Recheck by substituting back — 4 of 5 errors are caught this way.

Exam-day maths strategy

  1. First 10 minutes: read the whole paper, mark the questions in 'easy → hard' order.
  2. Solve the easy bank first — build early confidence and bank quick marks.
  3. Leave 10 minutes at the end to recheck sign errors and units on the short-answer section.
  4. Never blank a question — write the method you know; partial method = partial marks.

The last-10-minute rule

The most expensive mistake in a maths paper is a sign error you could have caught in 30 seconds. A 'silly-error scan' of the first 6 solved questions in the last 10 minutes routinely recovers 2–4 marks.

FAQ

Common questions

How can I score 90+ in Maths?

Master the NCERT examples and exercises, show every step in writing, practise most days, and protect easy marks by rechecking signs and units. 90+ is the normal result of that process.

Is scoring full marks in Maths possible?

Yes, especially in CBSE boards — the paper is NCERT-pattern by design. Full marks are lost to presentation and slips, both fixable habits.

How many hours a day should I study Maths?

An hour of focused daily practice beats a long weekly session. In board years aim for 1–1.5 focused hours on most days plus one weekend timed set.

How to present answers for full marks?

Given → formula → each step → boxed answer with unit. Examiners award step marks, so write the method even if the final arithmetic slips.

Why do I make silly mistakes?

Because of skipped steps and time pressure. Slow the start, box answers, and maintain a personal error list (signs, carrying, misreads) to scan before each exam.
