Bachelors

Hello, one should score at least 50% marks in graduation to be eligible for the admission process of IIM, Ahmedabad. CAT is the only exam whose score is accepted by it.

Diploma is a specially structured course that focuses only some certain aspects of the course. Bachelor degree is an all-round course and includes mostly everything. Diploma is mostly practical in nature and Bachelor courses are theoretical mostly. It is applicable to interior designing as well.

Yes, there are chances to get into services, through the degree you can write UPSC exams.

No, they take admission on the basis of your 12 marks.

If your goal is to pursue CA then definitely you should go for B.Com as it takes fewer efforts than BBA. So by taking B.Com and pursuing it you can prepare for CA very nicely.

The initial shortlisting of candidates will be done on the basis of CAT percentile and in your category it is above 90. So you are meeting the eligibility criteria here. The weightage of CAT percentile is the deciding factor here over other like 10th, 12th, Graduation and work experience etc. The contribution of CAT percentile is 75%, while others are responsible for 25%. Further personal interview and GD are the other activities of selection. So, in my opinion, you a call for admission.

B.Tech biotechnology does not required NEET exam. For good colleges or universities, it will conduct own entrance exam or common entrance exam. Some will provide admission on merit basis. If you want NIITS and all, then better to write JEE exam.
