J.J. College of Engineering and Technology Tiruchirappalli, Tiruchirappalli - community

My cousin got 4.5k rank in neet 25 but he isn't sure as to which college to join between sion, nair cooper and jj. He will try for kem but isn't sure as it is a tough clg to get. He wanted to join jj but recently he has found a lot of complaints stating that the academics is not upto mark which discouraged him. Is it true that the academics is not good?
