Greetings aspirant,

Percentile is a relative term, which depends on the Level of difficulty of the exam under consideration & how others performed in it. Lets assume you have scored 99.5 percentile in an exam, then you have positioned yourseld among top 0.5 percentage of the total test-takers. There is no exact method/procedure about the percentile calculation in MH CET exam so one can only predict or assume about it.

Although I would suggest you to use Careers360 college predictor for MH CET(https://www.careers360.com/mht-cet-college-predictor?ici=cahometool_lp&icn=mhtcetcollegepredictor-clgpd-trial) to assist you deciding your next steps.

Hope it helps.

All the best!
