Student & Academic Calculators

Grades and marks involve a lot of small, fiddly arithmetic — weighted averages, conversion formulas, how many classes you can still miss. These calculators do that arithmetic and show how they got there, so you can check it against your own mark sheet.
Grading rules differ between boards, universities and countries. Where a formula varies — CGPA conversion especially — the tool lets you pick the one your institution uses, or enter your own, and says plainly which one it applied.
