B.Tech

Sorry Vibhor as you have not mentioned the campus name of SRM University so it is not clear if you are getting NCR campus in SRM then you must go to Manipal University as Manipal is quite better than SRM NCR campus.

As your rank is 10500 you easily get KTR campus so I’d suggest you to go through computer engineering branch in counseling as your rank is low you have to report on 14th May sharp at 8 am in counseling according to the counseling letter.

Hello Karthik,
It's good to know your passion about Aeronautical Engineering. Yes it's quite an exciting field. And I want to assure that you using specs will definitely not hinder your passion.

You can join SRM University, Chennai as it has a good reputation and is considered to be a good private college for B.Tech. SRM University is one of the best institutes among top 10 private colleges in India.
So, be a part of it and do well in your future.
All the best.

The available scholarship in NSIT and DTU is on NSP website.
You can visit there www.scholarships.gov.in or www.nsp.gov.in.
Various scholarship for SC/ST/OBC are available but there is no scholarship program related to 12th %.

In Delhi, following are the best options for you:
DTU
NSIT
JMI
GB Pant

At present, both have equal placements, but ECE has a good reputation, so what others say as a brand, but it clearly depends on you. As a whole, I'll suggest is to test yourself for your desires & capabilities before deciding it as both are good here.

Stream changing option will be open for all students after completion of 1 year of their academic session not after 1st semester.
So keep your grades good in college and maintain GPA of 9+.

Sorry but 70 marks are too low to get you any college in Maharashtra.
So it is advisable for you to keep trying contact private colleges/university for direct admission on basis of 12 score.
