Mathematics is often regarded as one of the most scoring subjects in the CBSE curriculum. Yet, students frequently lose marks due to common mistakes that can easily be avoided with a little attention and strategy. In this blog, we’ll highlight the typical errors students make and provide actionable tips to help you avoid them and excel in your CBSE Maths exams. 💯
🔍 Top Mistakes Students Make in CBSE Maths Exams
1. Skipping the NCERT Questions
NCERT is the bible for CBSE exams, and many students underestimate its importance. Skipping these questions can lead to gaps in your preparation.
How to Avoid:
✅ Solve every example and exercise in the NCERT textbook at least twice.
2. Misreading Questions
In the rush to complete the paper, students often misread questions, leading to incorrect solutions.
How to Avoid:
✅ Read each question twice before starting to solve it. Underline key points to avoid missing details.
3. Careless Calculation Errors
Simple addition, subtraction, or sign errors can cost precious marks.
How to Avoid:
✅ Practice calculations daily and double-check your answers during the exam.
Common Errors | How to Fix |
---|---|
Forgetting negative signs | Re-check each step carefully. |
Adding fractions wrongly | Practice fraction problems. |
Decimal place errors | Use rough work systematically. |

4. Poor Time Management
Running out of time is a common issue, especially with lengthy questions.
How to Avoid:
✅ Allocate time for each section and stick to it. Start with the questions you’re confident about.
5. Not Drawing Diagrams in Geometry
Geometry questions often require diagrams, and skipping them can result in marks deduction.
How to Avoid:
✅ Always draw neat and labeled diagrams for geometry questions. Use a pencil and ruler for precision.
6. Neglecting Formulas
Forgetting key formulas during the exam can lead to incomplete answers.
How to Avoid:
