Frequently Asked Questions
Find answers to common questions about our student calculators and tools.
Are all student tools completely free to use?
Yes! All student calculators, GPA planners, and attendance utilities on EveryZap are 100% free with no subscriptions, accounts, or hidden paywalls.
Is my academic and grading data kept private?
Yes. All calculations take place strictly inside your web browser engine. We never store, log, track, or transmit your grades, course titles, or attendance numbers to external servers.
Can I use these calculators on smartphones and mobile tablets?
Yes. EveryZap is built with a fully responsive layout and touch-friendly controls, allowing students to check GPA and attendance on mobile phones directly on campus.
How do credit hours affect my GPA calculations?
Credit hours weight each course according to its instructional volume. A 4-credit course has twice the impact on your final GPA compared to a 2-credit course.
Can I convert my calculated CGPA to a percentage?
Some institutions use CGPA × 9.5 to estimate percentage. Always check your university, board, or institution's official conversion formula before using the result for admissions or applications.
