JEE

Chances are slim, though you have chance to get some decent government college through JEE itself try to get in those.
All the best.

All books are sufficient for the student who wants to study and no book is sufficient for those who don't have interest in studies.
So if you can understand the language of the books easily, you can opt for them. But if you aren't able to understand, then go for Arihant Publications or Pradeep Publications.

Most of the colleges offering food tech are accepting admission on the basis of JEE rank, so you have to appear for JEE Mains.
But no problem if you haven't appeared for the Mains; there are some institutes that are accepting admission only through their common entrance exam.
You can appear for those or can directly take admission in the college on management quota seats.

I think you should go for UPES, although fee structure of upes is very high. You cannot get any NIT with these marks. One most important point is that upes is not good for CSE.

Honestly, no one leaves CSE branch seat. If there's any seat left, students from other branches will take it. As you haven't given JEE, there's a very little chance to get admission in a branch of your own choice.
But yes, last year, at the end, admission to Thapar was open to all. You could get a seat in the branches available at that time.
Usually, Electrical, Chemical, Mechanical, Civil have some seats left.

JEE is not required abroad except for Germany. So if you have decided to study abroad better start researching on admission requirements and start preparing correctly instead of investing time with JEE. No two university will have similar requirements, you have to see these on university websites and prepare accordingly. Exams like SAT TOEFL etf will be required. Check your Budget.
