About these student tools
Grading systems differ between boards and universities, so these tools state their method on the page and, where institutions disagree, let you enter your own formula rather than guessing. CGPA-to-percentage conversion is the clearest example: the CBSE rule is published, but universities each set their own, so the page says so and offers a custom option.
Everything runs on your device. Marks, grades and attendance numbers never leave the page.
