Hello,

There is no cutoff as per branches. There are cutoff as per category and different college and universities has their own cutoff rank rang to intake candidates. You have to score above 550-590 to get an admission in MBBS. If you score above 500 then you will get BDS. If you are okay with it, you can go for it.

Prepare with a stratergy and cover the subjects with clear concept and makeing yourself confident that you won't get confused later. This is the main point which decreases the mark. In the exam hall, we get nervous and make more mistake.

keeping this point in your mind prepare as if you won't forget it ever.

Hope it helps!
