What Type of Questions Usually Come in CBSE Class 10 Maths Exam?
After getting to know the highest weightage chapters, you must be wondering if the questions are also repeated. No, CBSE does not copy-paste old questions. But it repeats patterns. So, during your revision, focus on these common areas:
- Algebra word problems from quadratic equations and arithmetic progression
- Proof-based questions from triangles
- Tangent properties and theorem-based sums from circles
- Mixed data table questions in statistics
- Application-based sums from heights and distances
- Surface areas and volume comparison problems
CBSE 10th Maths Last Minute Tips
- In the last few hours before the CBSE Class 10 maths exam 2026, focus on understanding the logic behind formulas and steps. If you understand why a method works, you will not panic even if the question looks a bit twisted.
- Despite the wide range of reference books available in the market, CBSE continues to form its questions mainly using the NCERT textbook, the NCERT Exemplar, official sample papers, and competency-based question banks.
- Solve 2 or 3 full sample papers properly. Not ten. Just two or three. But solve them in three hours like the real exam. This improves speed and reduces careless mistakes. Don’t stop there. After solving, carefully analyse where you lost marks. That analysis is more important than solving many papers.
- Avoid starting anything new now. This is very important. Do not open a new reference book or attempt extremely difficult extra questions at the last moment. Strengthen the chapters that are already scoring instead of trying to master everything overnight.
- Also, remember that CBSE gives marks for steps. Didn’t know that, right? But it is very true! If you cannot reach the final answer, still write the formula, show substitution, draw a proper labelled figure where required, and write logical steps. Even partial progress can earn you some marks.
- Most marks in board exams are lost because of small errors like sign mistakes, wrong squaring, basic calculation errors, or skipping units. In the last 15 minutes of the paper, recheck your calculations carefully, especially in Algebra and Mensuration.
- On exam day, stay calm. Attempt easier questions first. Do not get stuck on one tough problem for too long. Keep at least 15 minutes at the end for revision. Sleep properly the night before.
