Hello sumaiya,

If you have aggregate 75% in PCM and have more then 60% marks in physics,chemistry and mathematics you can get to BITs but for that you have work hard and perform well in the BITSAT exam to secure good rank.

No according to the eligibility criteria of BITs you need to have minimum of 75% as your PCM aggregate not your overall aggregate. If you have PCM aggregate as 75 then you're eligible to get admission in the college otherwise I would suggest you to look for some other colleges.

Thank you
