The Infrastructure of NIT Surat is quite impressive, the library here is probably one of the best among NITs. They have built new departments which are quite impressive, to be honest. The gym is good, but if you're interested in sports you might not like the facilities here.
The placements and Internship percentage are quite high and the students can get placed in some respected companies. You'd have to be an above average student to get internships in a pre-final year! and yes you don't need to worry about the quality of placement here.
There is a system of getting admission in the college and that is first you have to clear the basic percentage criteria given by the college and then you have to go for the counselling which is very common in the colleges of the state
For the student of mechanical like me the placements are very low but for the IT and computers, it is very High.
