Coimbatore

If you could tell me your rank in the AEEE examination then I may help you easily as the marks cannot predict the ranks, it is a dilemma whether you could get admission or not.

You have good chances of getting almost all the courses like chemical, civil, electronics, electrical, computer science, etc. as you belong to Tamil Nadu, your home state rank has made you eligible for the seat.

The admissions into Amrita University and its other campuses are based on the rank secured in AEEE. They don't consider JEE Mains marks as it is a private deemed university. Score a rank like 4000 to get Amrita University.

Both are really same in all factors. They are highly reputed institutions and offer good education and placements. So, you can prefer any one of these two colleges.
But, PSG Coimbatore is widely preferred to MIT-Chennai, even though both are equal. MIT is Government College, but PSG is a private college.

PSG College of technology, Coimbatore is better than SSN college of Engineering, Chennai. Both come under Anna university affiliation, but the standard of PSG and its reputation is higher than SSN College, Chennai.
