⚠️ Pass rules vary — some boards need 33% overall, others require separate passes in theory, practical, and internals, and grace-mark policies differ. Always confirm your board's official rule.
📌The line you must not miss — computed correctly
"What are the passing marks out of 80?" sounds trivial until rounding decides your result: 33% of 80 is 26.4, and since half marks aren't awarded, the real pass mark is 27. This calculator gets that right for any exam total and any pass rule, checks your score with the exact margin or shortfall, handles boards that demand separate passes in theory and practical, and gives you a ready-reference card of pass marks for every common exam total.
📊Everything you'd want to know
- Pass mark for any total at 33 / 35 / 40 / 45 / 50% or a custom rule — correctly rounded up.
- Optional score check: PASS with margin, or FAIL with the exact shortfall and a grace-marks pointer.
- Theory + practical mode where each component must clear its own pass mark — the way CBSE and most universities actually judge.
- A quick-reference grid: pass marks for exams out of 20, 25, 30, 40, 50, 70, 75, 80, 100, 150, 200, 300, 500 and 600.
- A colour-coded PDF pass-marks card with score bars.
🧮The maths
The ceiling matters: exam scores are whole numbers, so any fractional pass threshold rounds up — 26.4 becomes 27, because 26 is below the line. When theory and practical are judged separately, each component applies the rule to its own total, and failing any one component fails the subject regardless of the combined score.
💡Worth knowing about pass rules
- CBSE Class 10 & 12 need 33% — in board exams, and (for Class 12) usually in theory and practical separately.
- Most state boards use 33–35%; many universities set 40% per paper and 50% aggregate for professional courses.
- Grace marks exist almost everywhere (typically 1–5 marks or up to 1%), but they're discretionary and usually apply to one subject only.
- Internal assessment often has no separate pass line in Class 10 — but practicals in Class 12 do. Check your year's circular.
💡 Frequently Asked Questions
What are the passing marks out of 80?+
At the standard 33% rule: 33% of 80 = 26.4, rounded up to 27 marks — 26 is below the line. At 40% you'd need 32. The calculator's reference grid shows pass marks for every common exam total at your board's rule.
What are the passing marks out of 100, 70 and 600?+
At 33%: out of 100 → 33, out of 70 → ⌈23.1⌉ = 24, out of 600 → 198. Switch the pass percentage chip to your board's rule and the whole reference grid recalculates instantly.
Do I need to pass theory and practical separately?+
In most boards and universities, yes — each component must clear its own pass mark, and a brilliant practical can't rescue a failed theory paper. Use the theory + practical mode to check each component with its own total and rule.
What are grace marks and will I get them?+
Grace marks are a small discretionary boost (commonly 1–5 marks) that boards may award when a student narrowly misses the pass line, usually in a single subject. They're policy-dependent and never guaranteed — the calculator tells you your exact shortfall so you know if you're in grace territory.
Is 33% passing in all boards?+
No — 33% is common (CBSE and many state boards), but several boards use 35%, most universities use 40% per paper, and professional courses often require 50%. Set your exact rule with the chips or the custom field.
