Hello, 

With your Jee mains rank you can get admissions with CSE branch into  institutes like JECRC(Jaipur),  LNMIIT(Jaipur)etc.

Also you can get some government college through reap as they prefer Jee main score over 12th score. 

There's a chance of getting good college like MBM but there you will be having a branch different than CSE. 

Moreover, you can also try for Thaapar and Jaypee as they prefer Jee mains score for admissions. 

Hope this will help. 

Thanks.
