CBSE grade band
CBSE’s absolute grading assigns a grade by percentage range: A1 (91–100), A2 (81–90), B1 (71–80), B2 (61–70), C1 (51–60), C2 (41–50), D (33–40), E1/E2 (below 33). We map your percentage to the correct band.
Pass mark
The standard CBSE pass mark is 33%. A percentage below 33% falls in the E (Essential Repeat) band and is flagged as not passed.
