1. No of students
2. No of seats
3. Difficulty of paper
4. past year trends

With your rank in jee main you have less chances of getting a seat in nit Srinagar.

Srinagar doesn't have so much engineering college accepting jee main you can admission in those colleges based on their entrance examination.
