SRM university ranked first overall in India in private college’s. Coming to campuses there are Main campus(katankulathur),Ramapuram,Delhi-NCR,Vadapalani and Amaravathi(newly opened I guess).
Firstly coming to studies faculty from SRM-Ramapuram has less number of PhD profiled lecturer’s, most of the faculty is likely sort there knowledge. If you want good teaching facilities then join Main campus but dont get habited to culture otherwise studies will become fun out of it.
Placements: entire SRM university placement is held at Main Campus so oppurtunity for each and everyone is same irrespective of campus you are from.
