Student Calculators

Student life runs on numbers that decide whether you pass, what honours you earn, and how much you can afford to miss. The student calculators on this page turn a list of subjects or a couple of marks into the single figure you actually care about — your average, your attendance, or the score you still need. None of them store your data; everything is worked out in your browser the moment you type. **Averages: CGPA and GPA.** These two do the same kind of maths — a credit-weighted average of your grade points — but on different scales. The CGPA calculator uses the 10-point scale common in India (O, A+, A, B+ and so on), while the GPA calculator uses the 4.0 scale common in the US (A, B, C, D, F). Add one row per subject with its grade and credit hours; the calculator multiplies each grade point by its credits, adds them up, and divides by your total credits. Use CGPA when your transcript is on ten, GPA when it is on four — and use both to see how the same performance looks on each scale if you are applying abroad. **Attendance and marks.** The attendance calculator tells you the percentage of classes you have attended and, handily, how many more you can skip while still clearing a 75% bar. The marks percentage calculator is the simplest of the set — put in the marks you got and the total available, and it returns the percentage. Both are the check-you-reach-for before a parent-teacher meeting or a grade appeal. **The grade you need.** The grade calculator works backwards from a goal. Tell it your current grade, the weight of the final exam, and the grade you want overall, and it works out the exact score you must get on the final to land there. It is the fastest way to find out whether a target is realistic or already in the bag. Enter your figures, read the result, and adjust. Because the maths is instant and private, you can model "what if I score X on the final" as many times as you like before exam day.
