Rajasthan

There is no re-exam for RIE.

BITS-Pilani is the main campus. The main campus is better in term of crowd, infrastructure, faculty, facilities. The BITS-Pilani is far from main city, so the study environment is great. Don't be confused, go for Pilani campus.

No, you cannot change your college after 1st year in Rajasthan University. But, if you really want to change, then you have to change university and again start B.Sc from 1st year from another university.

College change or university change after first year is completely dependent on the college and university norms, some universities allow it and some won't. Plus, you need to have good scores in the first year to apply for the same. For further details, contact the college authorities.

Hi Aayushi, Ranking Order:
XIME
Christ University
Manav Rachna
RA Podar
I would suggest you go fro XIME as it will surely give you more edge as compared to remaining mention colleges.

You must have scored more than 125 marks to CSE branch in that for all other branches if you have scored more than 85 marks it is more than sufficient.

Follow the college predictor below for details and filter LNMIT:

I am not really sure if RIE, Ajmer gives an option of re-appear. Request you to contact the officials for the same.

Please tell me which govt. job are you looking forward to because every job has different selection criteria.
