About this tool
Weigh the re-check fee, the chance of a change and the deadline before applying for revaluation of an answer book.
This helper prices a revaluation application as what it actually is — a bet with a fixed fee and a two-sided outcome. It computes the expected change in marks as P(rise) × gain − P(fall) × loss, the cost of each mark you can expect to gain, and the break-even probability at which the application stops being worth the money, then checks the answer against the deadline. The downside is priced deliberately, because boards including CBSE treat the marks awarded after re-evaluation as final whether they are higher or lower than the original.

Counts the risk that revised marks come out lower, which most students ignore.
Gives the break-even chance of a rise, so you can judge whether your case clears it.
Counts the days left to apply next to the money at stake.
Yes. Under CBSE's Examination Bye-Laws and most university ordinances the marks awarded after re-evaluation are final, whether they are higher or lower than the original, and the earlier score cannot be restored. Verification or re-totalling carries less of this risk than a full re-evaluation, because it checks addition and unmarked questions rather than re-judging answers.
It is worth it when three things line up: the gain you realistically expect is at least as large as the gap to the mark you need, your grievance is specific rather than a general feeling, and the window is still open. A vague sense that the marking was harsh is a weak case; an entire question left unmarked, or a total on the front page that does not match the marks inside, is a strong one.
Re-checking, also called verification or re-totalling, is a clerical exercise: someone re-adds the marks and confirms that no question or page was left unmarked, without re-judging any answer. Re-evaluation puts a fresh examiner on the specific questions you name and can move marks either way. Boards usually require them in order — verification first, then a photocopy of the answer book, then re-evaluation of the questions the photocopy shows a case for.
The window opens the day the result is declared and is typically short — often a week or two for each stage, with the later stages having their own separate dates. Because the stages run in sequence, missing the first date can shut off the ones after it. Check the post-result circular on your board or university website on the day the result comes out rather than waiting; fees and dates are revised every year.
