Hi,
Without maths, you can't be eligible for M.Sc biotechnology in Techno India.

No, there will be 2 different certificate diploma and degree will be awarded.

IEM is one of the top institute for BCA in India. If you are thinking for take admission for BCA, then go for it. Curriculum and teaching methodology are perfect here. According to me, go for IEM.

IEM takes admission through WBJEE and JEE Mains and not through any other joint entrance examination. Your rank should be between 700 to 800 (GMR) to get into IEM. IEM offers 12 seats for mechanical students through JELET. Usually, if seats get vacated at the end of the first year and there will be a chance of admission through JELET. In Techno India Salt Lake City for lateral entries eligibility criteria is that a candidate should have minimum 60% aggregate in Diploma in engineering.
Hope this helps.

There are some chances to get admission, so you can try.
Good Luck!
