Many Class 12 students have this doubt before exams: can you use a calculator in board exams? The answer is mostly no, but there are a few important exceptions and updates you should understand clearly.
Final Answer for 2026
For the 2026 board exams under Central Board of Secondary Education:
- Calculators are not allowed in most subjects
- Accountancy may have a limited exception (subject to official confirmation)
- Students with special needs can use calculators with prior approval
Subject-wise Rules
Mathematics
- Calculators are not allowed
- All calculations must be done manually
- Questions are designed to test concepts and step-by-step solving
Physics
- Calculators are not allowed
- Numerical values are usually manageable without devices
- Focus is on formula application and accuracy
Chemistry
- Calculators are not allowed
- Approximation and basic arithmetic skills are expected
Accountancy
- There are recent updates suggesting that basic calculators may be allowed
- This is intended to reduce calculation load and allow focus on concepts
- However, this is not confirmed for every exam cycle
- You must check the latest official notification before relying on it
Exception: Students with Disabilities (CWSN)
- Calculators can be allowed for students with conditions like dyscalculia
- Prior permission is required
- Approval must come from the school and the board
Why Calculators Are Not Allowed
The board follows a clear approach:
- To test conceptual understanding instead of device dependency
- To maintain fairness among all students
- To ensure students develop strong calculation skills
Important Reality for Students
Even if there are discussions about allowing calculators in Accountancy, you should not depend on it.
Prepare as if:
- You will not have a calculator in any subject
This approach ensures you are fully ready regardless of last-minute rule changes.
Comparison with Competitive Exams
- Exams like NEET and JEE do not allow calculators
- Fast manual calculation is an essential skill
Your board exam preparation helps build this foundation.
Practical Preparation Strategy
To perform well without a calculator:
- Practice manual calculations regularly
- Improve speed in multiplication and division
- Learn basic squares, cubes, and approximations
- Solve previous year papers without using any device
Final Note
Rules can change slightly each year. Always verify updates from Central Board of Secondary Education before your exam.
The safest strategy remains simple: build strong calculation skills and avoid dependence on calculators
