Joining REVA University through COMED-K or management quota is a complete waste of money. You will be paying 3.5 lakhs per year which is not worth it. You will get many better colleges.
If you are considering it via CET, I would suggest you not opt for the university. Try for other better colleges.
The college does not publish its placement reports on its website because it is not good. You can ask about it from the seniors of the college and you will find out that only 20-30% of the students get placed.
The teaching faculties are mostly freshly M.Tech passed out students and hence, lack experience. The student intake for B.Tech is 3000-4000 students in every batch which is way higher when compared to other colleges which usually have an intake of around 900 students.
