For joining ISRO, first you may have to appear for ISRO test. Eligibility criteria is given below:

It is not bad for MBA but better to avoid for PGDM like costly investment and give entrance for better score. Probably, you are investing a huge amount for a life time career and not just a degree with uncertain job profile. I was alumni of one of the above college. So, I can have some words for you before you invest.
Here are some of the parameters to choose that how to judge an average B-School:
1) Try to avoid trust in morphed media ranking (not all media), sometime it happens to promote the college brand name in students mind.
2) Don't run or get lured by the call of 100 percent placement. If you are in, bulk hire and fire offers are offered. It does not make any sense to you.
3) Don't run behind INR 9.6 Lacs CTC per annum. Always check in hand salary or take home salary.
4) Check the job profile and not the brand name.
You may enjoy the service of famous bank ACIZ, but may not enjoy it as an employee, if your profile is unrealistic target based financial product sales job.
5) Try to avoid NGO Agency, as they will make gigantic promise and push you in a poor B-School to make money from the college.
6) Try to avoid the views of current students, as being a part of system. They can't criticize it or put the real pic in front of you.
If you have all the satisfactory answer from placement officer, then join or don't go and give MAT/CMAT once again to chase tier-I colleges SIMSREE (Govt of MAH), PUMBA (Government), XIME Bangalore, Great Lakes Chennai, IFMR, BIMTECH (Retail), NL Dalmia (core finance), XIME Kochi, TAPAI Manipal, IMT Nagpur (sales), IMT Hyderabad, etc. Remember, as you are paying 100 percent cost, so you deserve the 100 percent value. Don't compromise with this at any cost. Otherwise, you investment may backfires you.
