Dear candidate out of the two college options chosen by you, both are wise ones, however based on the academic facilities I would keep CR Reddy Institute somewhat above than Acharya Nagarjuna University. This is because CE Reddy Institute has got plenty good faculties, helpful guidance from all the staffs and coming to placements they will provide you starting salary package of 3-5 LPA.
