Marks and GradesThe first calculator
Give the marks you already have, the maximum of the papers already written and the maximum of those still to come. The calculator finds the total needed for your target, subtracts what you have, and tells you the marks and the percentage you need in what remains. If the target can no longer be reached, it says so and shows the highest percentage still possible. For a single subject with internal marks, treat the internal marks as "scored so far" and the written paper as "left".
The second calculator
It multiplies the maximum by the pass percentage. When the answer is a fraction it also gives the next whole mark, since a mark sheet shows whole marks and a mark below the line is below the line. Boards differ on rounding and on grace marks, so treat the whole-mark figure as the safe target. Remember that some rules have more than one condition: the CBSE bye-laws require 33% separately in theory and practical in class 12 subjects with practical work. See CBSE pass marks and ICSE and ISC pass marks.
The third calculator
It works in credit points. Your CGPA so far times the credits completed gives the points you hold; the target times all credits gives the points you need; the difference, divided by the credits remaining, is the average SGPA you must earn from here. If that is above 10, the target is out of reach, and the calculator shows the best CGPA still possible.
Use the answer to plan
Aim a little above the figure shown. The guide how many marks do I need? explains the sums with examples.
Questions people ask
How many marks do I need to pass out of 80?
At 33%, the exact figure is 26.4, so 27 whole marks. At 35% it is 28. At 40% it is 32.
How many marks is 33% of 70?
23.1, so 24 whole marks reach the line.
Can I still get 90% overall?
Enter your marks so far, the maximum already done and the maximum left with a target of 90. If the marks needed are more than the marks left, it is no longer possible, and the calculator shows the best you can reach.
Does the calculator include grace marks?
No. Grace marks and rounding are decided by each board and cannot be counted on.
