Frequently asked questions
Which grading systems do the GPA tools support?
The 10-point scale used by Indian universities, with the UGC letters (O, A+, A…) or the AA, AB, BB style used by IITs and NITs. The converter covers the CBSE × 9.5 formula and the other common ones.
How current are the exam dates?
They're checked against official announcements and marked official or expected. The countdown pages show the date they were last checked.
Is anything I enter saved?
Inputs stay in your browser and in the page link, so you can bookmark or share a result. Nothing is sent to a server.
Do the timers work offline?
Yes. Once loaded, the Pomodoro timer, countdowns and typing test keep working without a connection.
