Engineering

Yes, few north eastern NITs are very good compared to their state colleges like NIT-Silchar in Assam, NIT Sikkim, etc. In NIT, you will get more better infrastructure, platform, faculty, environment compared to the state colleges.

Yes, B.Sc Computer Science is available in Punjab University. There are total 34 seats in this and for getting a seat in it you have to clear PUCET exam.

Yes, you can apply for JEE counselling on JoSAA portal. JEE cutoff is just for advance exam selection. So, you can do choice fill up on JoSAA, and even you can get colleges if it comes under any rank range of a college. So, do choice fill up well.

You can check that, you may get an admission in Thapar University or not by following link:-

Hello,
The cutoff percentile is kept at 54.01 by JoSAA for seeking admission in NIT. If your percentile is this or better you can definitely bid for admission. To help you I am attaching a link that will predict college for you based on your performance in JEE Mains. https://www.shiksha.com/b-tech/resources/jee-mains-college-predictor
Best wishes.

F. W. means Fee waiver. F. W. quota is applicable for those students who are economically weak (i.e. less than 100000 family income) and good in academic. If you take admission through counseling then you can avail it. Every college affiliated with state university has at least two seats. It varies on seats allotted to college.

Good, here I am unable to understand what you want to know can you explain clearly.

Why not, apart from getting admission in IITs, your success story will be published in top newspapers also. It's really good that a 16 year old student is clearing JEE advance. Also, you will be an engineer at the age of 20. It is really great, if you make it. Work hard. Nothing is impossible. Best of luck.
