JEE Main Percentile

At the outset, congratulations for your good percentile in JEE Mains paper 2. you can get seat in any of the architecture college in India. If you are aiming to top institutes then it is not a piece of cake.
All the best.
Feel free to clarify any query.

Under general, you can get admission in Computer Science engineering at NIT Durgapur. And as of my opinion, you should choose discipline of your own interest instead of getting any random branch.

You have got very good marks. You have a very good chance of getting reputed NIT CSE branch though from a general quota. You may also try for IIIT Hyderabad if you are highly interested in CSE. I hope you got the answer of what you wanted to know.

You should appear in counseling. There is a chance of getting a lower NIT fir this rank. You may get a lower branch in a medium NIT too. So, appear in counseling and choose list wisely.

See, this is the first time of the new circular of this exam so it is difficult to tell you the exact rank, but as per the previous trend, you can expect a rank not more than 30K.

Most probably the chances are that you will get it. But for now, you will have to wait for it till the criteria come out. Also, it varies from year to year.

2019 will be the first time JEE Main results would be declared in terms of percentile, so there is absolutely no data to predict what percentile you would require to get into a good NIT. You could still get an idea about how much you need to score in terms of marks, which will be pretty much as same previous years:about 210+ for top branch in top NITs, 180+ for other branches in top NITs, 150+ for other NITs.

Yes, absolutely you will get and don't worry you will get top NIT as well as prepare good for advance because you performance is judged there. Revised all specially chemistry, because it will increase your rank in JEE advance and formula of physics keep in mind. Best of luck.
