Hi dear,

Yes if you have opted pcmb then you must have to give both the subject exams. And in general category you must have to score 50% and if you have domicile of Maharashtra then you must score 45% .

In order to get a seat in pcmb group you should have to pass the papers with above percentages, and have to crack MhCet exam with a decent rank.

I hope this help,
