Frequently Asked Questions
What is the CBSE Best of 5 rule?
CBSE mandates that English is compulsory in the Best of 5 calculation. Then the best 4 marks from all other subjects are picked automatically. This total (out of 500) is used for the final aggregate percentage and CGPA.
How do I convert CBSE percentage to CGPA?
CGPA = Percentage ÷ 9.5. So if you got 85%, CGPA = 85 ÷ 9.5 = 8.9. Conversely, Percentage = CGPA × 9.5.
Does CBSE still follow Best of 5 rule in 2026?
Yes. CBSE continues to follow the Best of 5 rule for Class 10 aggregate calculation. Always verify with the current official CBSE guidelines for any updates.
What if I have 6 or more subjects in CBSE?
If you have more than 5 subjects, CBSE automatically picks English plus your 4 highest-scoring subjects. This calculator does the same—enter all subjects and it will auto-select the best 4 non-English subjects.
