B.Tech Eligibility

Hi Siddhant,
It is difficult to say, as Xavier's cut-off varies every year, but it is somewhere around 75% always.

Yes, you are eligible for M.Sc biotechnology. You can check University's website for detailed fees structure in admission section.

Hi,
If you are doing B.Tech then reapplying for a B.Tech course again will not be accepted easily, so first you decide what to study. If you want to quit your current course and reapply even this will be challenging. Anyways if you are highly academic and have very good percentage you can give it a try. A very good SOP and LOR from your teachers will be required. If you want to transfer between semester you must then talk to the universities about their norms. You have to take the IELTS as well.

Admissions are on the basis of MHCET exam and its rank

Well without SRMJEE you can go through management quota.
