IIT Counselling

No, you won't so don't wait for JoSAA. Try looking out for other options.
All the best.

It's all on your interests. According to your marks, you can easily pursue B.Tech in IPU. But, if you have full faith that you can crack the next year IIT entrance exams, then only go for one year drop. Otherwise, if you have doubt then do not take a risk of one year. My suggestion is don't go for one year drop, pursue B.Tech in USIT, and then score good in college. All the very best.

Being an SC candidate, you need atleast 65% aggregate marks. It is 75% for general candidate.

According to 2018 NIRF ranking SRM University is 46th place and it is A grade university and Jain university is B grade university.

Hello Awdhesh,
Yes, you can get a college via JEE counseling. But you may or may not get a top college or the course you wish to get. It is difficult to say your rank as it depends on the number of candidates and their scores.
All the best!

I don't know about the reservations, but for admission in a good NIT, you don't have to wait for the JEE Advanced score, you can get admission to the college by getting at least 250 marks in the JEE Mains exam.
