Jaipur

In SKIT for admission the priority is given to JEE score.
In VIT admissions to the B.Tech courses is done through counseling on the basis of rank scored in Rajasthan Engineering Admission Process (REAP) which is conducted annually by Rajasthan Board of Technical Education. For more information visit: http://www.reapadm.com

In my opinion, IMS - Noida is the best according to the rank given by the India Today and Outlook Magazines.

It depends on your marks.

In NIT Patna, you can get any branch for sure in this rank but in MNIT Jaipur you may and may not according to the last year closing ranks. for more queries, go through the below link:

Yes, you can get direct admission in SKIT, Jaipur.
If you fill the form of REAP exam then you can take admission in SKIT through the counselling process.
Otherwise, you have to apply for the direct admission.

I think you should choose CSE in Jaypee Noida SEC 62. Manipal Jaipur is not as good as it's main campus. Jaypee is best private engineeing college in Noida. Placement is also very good there.

Dear lavakumar,
It's a difficult question to answer. On the safe side, if your percentile score is higher than 90, you have higher chances of conversion. Here main weightage is given to GD-PI process (around 50%).
