The eligibility criteria of the course require any 10+2 qualification with Physics, Chemistry, Biology, and English with a minimum aggregate of 45% for the general category and 40% for SC/ST/OBC categories. Yes, you are eligible to apply for a B.O.T. course in Mahatma Gandhi University.

Since you have completed your 12th standard with Physics, Chemistry, Biology, and English, you are eligible for the minimum criteria, but the final selection to the course would depend upon the individual process adopted by the concerned university, which in some cases is done through an entrance exam and, on other occasions, based upon merit.

Eligibility criteria and the admission process, year to year, might vary.

So I would like you to refer the Mahatma Gandhi University website or contact their admissions office for proper and latest information.

You can also visit their campus or contact their admissions department for more clarification and guidance.
