About Wapuula Tools

Wapuula Tools is a free set of grade, GPA and marks calculators for students — weighted grades, "what do I need on the final?", GPA, pass/fail checks and quick averages. Every calculation runs entirely in your browser: nothing is uploaded, nothing is stored, and there is no login.

We pair the tools with plain-language grading-scale references. Grading data is presented as reference, clearly sourced — never an official ruling. Boundaries change and vary by institution, so always confirm with your own school, board or university. See our methodology and disclosure.
