MBA/PGDM

Yes it is. With the implementation of IIM Bill, now IIMs can also offer MBA degrees.

Your acads are on the lower side for a call. Still I would suggest you to secure very high CAT percentile (upwards of 99.8 percentile) for increasing your chances for a call.

Top parameters for selection into a top B-School in India: A good CAT score, good academics, good work-experience and of course, a good performance in the interviews.

IIM A is considered as the best Management college in India & is ranked 16th in the world according to FT MIM Ranking.

Your acads are not up-to the mark for a call from IIM A. I would suggest you to look at colleges which give less importance to acads like FMS.

You will need upwards of 99.6 percentile for getting a call from IIM A (Assumption: You are a GEM & you have 90%+ in 10th/12th & 85%+ in Grad). In case you do not satisfy the percentage criteria provided above, the percentile requirement for a call will be higher.

Approx fees: INR 20 Lakhs

INR 20 Lakhs (All inclusive except food expenses).

If you are referring to Executive MBA, then yes of course. But if you are referring to ePGP (long-distance MBA) then NO.

Dear,
With B.Tech Aeronautical Engineering, you should plan for M.Tech for better opportunities and better job profile.
MBA Aviation has different job prospects and your job profile would be different and if you are interested in technical research than MBA will be not a good choice.
All the best.
