Hello Subhanka, See after MAH CET result, college will invite you for counseling process or CAP (eg:-PUMBA - pune university)... and once this round got clear, then they will disclose the merit list of the finalized candidates. (final stage to MAH CET participating institutions will start from May 2018)... Gud Luck

After the announcement of the MAH CET  result, candidates will be shortlisted on the basis of cutoff score, thereafter called for the counselling process or the Centralized Admission Process (CAP), to avail the final admission to the respective MAH CET participating institutions that will be held in May 2018.

Good Luck!
