JEE

Yes you can easily get NIT through SC reservation. For your state NIT it is almost sure and for other top NIT it may not sure but for lower NIT it is again sure that you will get admission. But branch may be different from your choice.

Yes, don't worry you have to chance to get NIT with the CS branch.

You can get very Few NIT's or IIIT's if you are from General Category but if you are from reservation Category then there is high chance of getting NIT's or IIIT's but branch will be different there. Also you can get into GFTI's if you are from reservation category. Now talking about private college, here you can almost all of private colleges.

You can get many government colleges like NIT's, GFT's, IIIT's or good state government college of your choice. For getting better idea firstly you should sit in JoSAA councelling, here you will get clear idea about which college and branch you will get. But before applying to JoSAA councelling, do some research related to past cutoff for different college and branch. Also try to first apply for your state NIT's, GFTI's, IIIT's because here you will get benefit of state quota.

Admission in DTU, NSUT or IIT Delhi for B.Tech Course can't be get through CUET as they don't allow to do so. To get admission there you should cleared JEE Mains examination with good Percentile, then you will be applicable.

Since you are from SC category so you can easily get admission in many NIT's, GFTI's but for getting a seat in IIT you should first appear and clear JEE Advance Examination and after that on score of JEE Advance you can get admission in IIT. Now in NIT's, GFTI's also you will get different branches depending upon their cutoff and your rank. So you should seat in Councelling conducted by NTA commonly known as JoSAA Councelling where they conduct around 6 to 7 rounds to fill the seat and in each round they release the cutoff for different college and Branches. Hope this will help you.

Firstly if you are from General or OBC or EWS category then there is no chance of getting CSE in any government college. If you are from SC or ST category, then there is also very low chance of getting CSE in good government college. So if you want CSE then you should try for any private college near you either it be Amity university or LPU or CU or JP university or VIT or SRM or any other.

No it's not
Just check the cutoff of JEE Main
It literally gives false information.

1. DTU
2. NSUT
Delhi region best engineering Colleges.

Actually, your percentile is too low.
For that reason, you are not able to get CSE in any NIT or IIT.
