Sometimes, students want to calculate theory exam percentage separately.

Example for Maths:

• Theory exam = 80 marks
  
• Internal assessment = 20 marks
  

If you scored:

• Theory = 64
  
• Internal = 19
  

Then total = 64 + 19 = 83/100

But if someone wants the theory-only percentage:

\frac{64}{80} \times 100 = 80\%

This is useful for:

• Scholarship forms
  
• Schools that ask theory-only marks
  
• Science/commerce admission cut-offs
  

6. How to Calculate CGPA to Percentage for CBSE?

(For previous years when CBSE used CGPA)

If your marksheet shows CGPA, use this formula:

\text{Percentage} = \text{CGPA} \times 9.5

Example:

If your CGPA is 8.2:

8.2 \times 9.5 = 77.9\%

This formula was officially used by CBSE.

7. Common Mistakes Students Make While Calculating Percentage

7.1 Mistake 1: Counting 6 subjects instead of 5

Only the best five subjects are counted.

7.2 Mistake 2: Ignoring additional subject rules

The additional subject automatically replaces the lowest-scoring main subject.

7.3 Mistake 3: Wrong total marks assumption

Remember:

• Maximum = 500 (for 5 subjects)
  
• Not 600
  

7.4 Mistake 4: Mixing theory and practical marks

Use total marks (theory + internal) unless asked otherwise.

8. Why Do Students Need Percentage Calculation?

CBSE does not print the percentage on marksheets, but students need it for many purposes:

✔ Admission to Class 11

(subject selection: Science, Commerce, Arts)

✔ School merit lists

(especially in private schools)

✔ Scholarship forms

(government or private)

✔ Entrance forms and registrations

✔ Resume or career forms

(Some require 10th percentage)

✔ College admissions later

Hence, knowing how to calculate the percentage correctly is essential.

9.4 Write neat answers

Presentation affects marks.

9.5 Practice diagrams and labeling

Important for Science and Geography.

9.6 Revise regularly

Revisions improve memory and confidence.
