Scoring 425 out of 500 is 85% — grade A2 on the CBSE 9-point scale, with grade point 9.0. The scale runs from A1 (91–100, grade point 10) down to E2 (0–20, fail), and you need 33% in each subject to pass. CBSE also calculates your CGPA from the best five subjects out of six, dropping the lowest.

How to get useful results from Grade Calculator
How CBSE grades work
CBSE uses a 9-point grading scale from A1 (91–100, grade point 10) down to E2 (0–20, fail). For Class 10 the bands are absolute: your marks fall in a fixed range, so 91 to 100 earns A1. For Class 12 the same labels are positional — CBSE ranks all students who passed a subject and awards A1 to the top one-eighth, A2 to the next one-eighth, and so on. The bands in this tool are the Class 10 absolute ones.
Per-subject grades
Each subject gets a grade from its percentage: marks divided by total, times 100. A subject at 87 out of 100 is 87%, which is A2 with grade point 9. To pass a subject you need 33% — and for Class 10 that means 33% in theory and 33% in internal assessment separately (27 out of 80 in theory, 7 out of 20 internal). Passing one and failing the other is a fail in that subject.
Best-of-five
CBSE calculates CGPA from the best five subjects out of six — the lowest subject is dropped. With Maths 87, Science 76, English 82, Hindi 68, Social Science 91 and Computer 59, the best five total 404 out of 500 (80.8%, grade B1) and the grade points 9 + 8 + 9 + 7 + 10 average to a CGPA of 8.6. The same rule is used for ICSE percentage: best five out of six.
Weighted grades
Not every subject weighs the same. A 100-mark subject contributes twice as much to your overall percentage as a 50-mark one, because the overall is total marks divided by total maximum — not the average of the subject percentages. Enter each subject's own total and the tool weights them correctly.
How much do you need in the final exam?
The marks you need are (target % × total marks including the final) − marks scored so far. If you have 320 out of 400 so far and the final is out of 100, reaching 80% overall needs 0.80 × 500 − 320 = 80 marks in the final. If the number is higher than the final's total, the target is not reachable — the tool tells you the maximum you can reach instead.
ICSE and other boards
ICSE (Class X) needs 35% in each subject and 33% aggregate to pass, with English a compulsory pass — and it also uses best-of-five for the percentage. CBSE needs 33% per subject. State boards set their own pass marks, usually 33% or 35%. If your board is not CBSE or ICSE, use the marks and totals here and check the grade bands against your own board's scale.
Common mistakes
The most common mistake is averaging the subject grades instead of the marks — grades are bands, not numbers, and averaging them gives a wrong overall. The second is forgetting that theory and internal assessment must each be passed separately. The third is using the Class 10 absolute bands for a Class 12 result, which is positional. And the fourth is converting a percentage to CGPA by dividing by 9.5 and calling it the grade-point CGPA — the two measures differ, so use the CGPA tool for conversions.

Answers
Frequently asked questions
What grade is 85%?
A2, with grade point 9.0. The A2 band is 81–90%.
What is the CBSE 9-point grading scale?
A1 91–100 (10), A2 81–90 (9), B1 71–80 (8), B2 61–70 (7), C1 51–60 (6), C2 41–50 (5), D 33–40 (4), E1 21–32 (fail), E2 0–20 (fail).
How is CGPA calculated from grades?
Take the grade points of your best five subjects and average them. With points 9, 8, 9, 7 and 10, the CGPA is 43 ÷ 5 = 8.6.
What is best-of-five?
CBSE and ICSE calculate the result from your best five subjects out of six — the lowest subject is dropped. It raises the overall percentage and the CGPA.
How many marks do I need to pass CBSE?
33% in each subject — and for Class 10, 33% in theory (27 out of 80) and 33% in internal assessment (7 out of 20) separately.
How is Class 12 grading different from Class 10?
Class 10 uses fixed mark bands. Class 12 uses positional grading: A1 goes to the top one-eighth of students who passed that subject, A2 to the next one-eighth, and so on.
What is the ICSE pass percentage?
35% in each subject and 33% aggregate, with English a compulsory pass. ICSE also uses best-of-five for the percentage.
How much do I need in the final exam to get 80%?
Use the final-exam mode: (target % × total marks including the final) − marks scored so far. At 320 out of 400 with a 100-mark final, you need 80 marks.
What happens if I fail one subject?
A mark in the E1 band (21–32%) puts you in the compartment category; E2 (0–20%) is a fail. You reappear for that subject under your board's compartment rules.
What is a weighted grade?
The overall percentage weights each subject by its total marks. A 100-mark subject counts twice as much as a 50-mark one — it is not a simple average of subject percentages.
How do I calculate my grade from marks out of 80?
Convert to a percentage first: marks ÷ 80 × 100. Then read the grade from the 9-point scale — 68 out of 80 is 85%, which is A2.
What CGPA is 85%?
It depends on the method. The grade-point CGPA from the example subjects is 8.6; dividing the percentage by 9.5 gives 8.9. Use the CGPA tool for conversions.
