Understanding Subject-wise Grades vs Overall CGPA
- Subject-wise grade — based on marks in that specific subject (theory + internal assessment).
- Overall CGPA — average of the best 5 subject grade points.
- Additional subjects — if you take a 6th subject and score higher, CBSE considers the best 5 for CGPA.
How Grading Affects College Admissions
For Class 10
- Most schools and boards accept Class 10 CGPA for stream selection (Science/Commerce/Arts).
