Look there are 3 streams of cse in thapar and about 400–500 seats in cse department whereas 4–5 years back only 700 students are admitted in thapar including all the streams.
Due to increment of seats and fees thapar has degraded a lot.
Students who score >158 of outside punjab and >135 for punjab are admitted last year in cse.
So quality of students has also fallen.
One of my uncle is library incharge there so told me that out of total batch lets say 100, got package >10 lac and others get around 4–5 lac .
His own son was studyind cse there and got package of 4.5 lac in the year 2014.
Among the private colleges BITS, IIIT H , IIIT banglore they are the ones you can look for.
I hope this can help you a little bit.
