Free tools for coaching institutes

TutorDesk publishes free tools for the work coaching centres repeat every week: generating printable OMR sheets for a test series, converting marks to rank and percentile, and planning batch capacity against enrolment and waitlists.

Percentile conversion depends on the cohort it is calculated against. The tool states which cohort it assumes; a national percentile cannot be derived from a centre’s own results.

The percentile calculator is the one worth reading the notes on. A centre’s internal percentile and a national percentile are different numbers, and quoting one as the other in a results sheet is the kind of claim that gets a centre a bad reputation quickly.

Caveat
Percentile depends on the cohort
01

Percentile is a claim about a cohort

A student in the 92nd percentile of your Sunday test is in the 92nd percentile of the people who sat your Sunday test. That is a useful number internally and a misleading one on a poster.

The calculator states the cohort it is computing against and will not present an internal figure as a national one. If a competitor’s results sheet does not say which cohort it used, it is worth asking.

FAQ

Questions people ask

Phrased the way they arrive, answered so each one stands on its own.

Can I generate OMR sheets for my own test series?

Yes, printable and free, with the question count and options you set. Scanning them back requires a scanner you already own; we do not sell hardware.

How is percentile different from rank?

Rank is your position in a cohort; percentile is the proportion of that cohort you scored above. Both are meaningless without knowing which cohort — a centre-level percentile and a national one are different numbers.
