Frequently Asked Questions
How do I calculate my 12th board percentage?
Add your total obtained marks across all subjects (e.g., 412) and divide by the total maximum marks (e.g., 500). Multiply by 100 to get your percentage (412 ÷ 500 × 100 = 82.4%).
What is the formula for percentage calculation?
The fundamental formula is always: (Value / Total Value) × 100. In exams, it is (Marks Obtained / Total Maximum Marks) × 100.
Do all subjects count equally in 12th exams?
In most 12th boards (HSC, Inter, CBSE Class 12), all 5 main subjects hold equal weight when calculating your aggregate percentage, but double-check your specific State Board rules.
