Passing marks out of 80 is 27 marks. Most Indian boards including CBSE require 33% marks to pass. 33% of 80 = 26.4, which is rounded up to 27. So a student needs a minimum of 27 marks out of 80 to pass. For exams with 20 marks internal + 80 marks theory, the combined pass percentage applies.
Passing marks out of 80 = 27 (33% of 80 = 26.4, rounded up to 27).
CBSE requires 33% to pass — both theory and internal assessments separately.
For 80-mark theory paper: 27 marks to pass; for 20-mark internal: 7 marks to pass.
Formula: Passing marks = (Pass%) × Total ÷ 100.
CBSE Grade D = 33–40 marks out of 100 (just passing).
UP Board, Rajasthan Board, and most state boards also use 33% pass criterion.
Calculation: • Pass percentage: 33% • Total marks: 80 • Passing marks = 33% × 80 = (33/100) × 80 = 26.4 ≈ 27 marks
Minimum passing marks out of 80 = 27
CBSE Passing Criteria: • Theory paper (80 marks): minimum 27 marks (33%) • Internal assessment (20 marks): minimum 7 marks (33%) • Overall (100 marks): minimum 33 marks (33%) • Must pass both theory AND internal separately in CBSE
