Manipal

First of all congratulations for your results!!
If you get that there is no issue of branch. You should take as per your field of interest. You are more likely to get all good branches like CSE,ECE and aeronautical as well. You can try for that.
Hope this helps you.

You may get the main campus but getting the desired branch may be difficult but yes if you don't have any specific branch choice then you can get the main campus.

Sikkim Manipal is average but the CSE department is really good in terms of faculty members and placements.

CCE is an upcoming field and offers you the best of CSE and well and ECE. It teaches you more coding languages than CSE and also teached the hardware parts. The placements have also been amazing. You get an advantage over companies during placements also.

No, there is no scholarship based on 12th marks. Students are eligible for scholarship only based on MUOET rankings.

Hello,
Be it any university which is comes under UGC Norms is a good choice, however for government jobs they mostly preferred Regular MBA. But private job company can consider no issues. Couple of more university which you can also consider. Mewar University
Suresh Gyan University.

With this rank, you might get main campus of Manipal University. So, you can try to get admission in Jaipur Campus. And, they will provide you good placement.
