Hii, Andru 

The answer to your question will vary from college to college , caste to caste and state to state in which you reside.

Answering your question with a general overview:but to get into a good college you will have to try and score more than 400 out of 720 marks.

My answer will change once you provide your further details like caste , state, prefered college.

Hpoe your query is answered.If you find any thing inappropriate please do revert back.

All the best.
