JEE Main

Very difficult. Seat allotment cannot be assured. This statistics can go up or down. Each year, the preference of students change. There is a 50-50 chance.

You need to qualify NATA and JEE exam for this campus. So, it's not possible to get getting admission easily with JEE Mains exam only.

All HSC students can write JEE. But to get a valid score in JEE, you have to pass the plus two and should score above 60%.

You can go for NIT-Warangal, Raipur and Calicut.
All these are very good options.

Top engineering colleges where JEE Mains score may not be required:
Birla Institute of Technology and Science, Pilani
Netaji Subhas Institute of Technology, Delhi
Maharashtra Institute of Technology, Pune
College of Engineering, Anna University, Guindy
Manipal Institute of Technology, Karnataka
VIT University.

You can go to colleges like Acharya, Alliance, CMR, etc. All these colleges will accept these marks.

Yes, sure you can expect a seat in SPA-Vijayawada with 232 marks.

You can expect NITs since you are from SC category. Also some Tier 1 campuses like ITM and Jaypee. All these campuses have very good placement ranging from 4 LPA to 6 LPA.

No, you can't get AKG at this rank.

I think you should choose Seemant Institute of Technology because LU doesn't have any good placement record and B.Tech is a newly launched course in Lucknow University.
