UPES

I am really very sorry to tell you about UPES for the M.Tech HSE that you have to have more than 75% in your B.Tech so that you can take admissions in UPES for M.Tech. University of Petroleum and Energy Studies is a very good college but as your percentage is quite less, so I would suggest you to take admission in some other college as UPES does not give admissions to the students those who have scored less than 75% in class 12th as well.

UPES does provides specialized course, but SRM Chennai is all the way know for it's better placement and quality education. Regards.

UPES is a better option based on their previous year results.

Ok, as per your question, my answer will be like 15000 - 30,000, you may earn after completing BBA in aviation in UPES.
But these figures will increase gradually and once you complete MBA, then it will hike with double of it.

If you want to enjoy your campus life and want to enjoy the life of the college just like as it is seen in the movies or in the serials, then you should take admission in Amity. But, if you are willing to enjoy the nature, want to study, and also want to enjoy the college life, then take admission in Petroleum University. In Amity, you will be enjoying the campus life because they call very huge actors and actresses in their college but when we talk about Petroleum University. They do not organise such a great event because they only focus on studies.
So, the conclusion is for campus life- Amity and for studies-Petroleum University.

According to me, the best university for petroleum and energy studies is UPES. There you will get a lot of opportunities in your 4 year programme. It has a very good infrastructure as compared to SPM and Jaipuria, Noida. It has very high tech lab and also they have a high tech library when compared to SPM, and Jaipuria, Noida.

Yes, it is better than most of the other institutes as far as BBA/MBA in aviation management is concerned.

No, second thought if you have to chose between UPES or NCAAS- for BBA or MBA UPES is better choice.

Both are very average, you should go for Symbiosis, SMU-DE, Welingkar, NMIMS, Amity University-Noida for online cum distance MBA. PGDM and MBA are equivalent, but PGDM has better industry specific curriculum. Hope this helps.
