Hi Shivam, 

If you have state quota, you have a very good chance to get a seat in CSE department of Heritage. However, if you are trying through All India Quota it might be a bit difficult but if you wait till the last round of counselling then you can get a seat if we consider the last year cutoffs.

You can check the final cutoffs from last year if you visit the following link:

Hope this helps,

Good luck!
