SRM Institute of Science and Technology, Kattankulathur

Yes, it is approved.

Yes, you are right as the SRM is now become a brand but the main campus is best. SRM Andhra Pradesh is just only using the name of SRM for marketing and they take large amount of fee which is not good to invest. If you want to invest such amount, you must try KIIT University.

Valiammai is one of the good campuses of SRM University, Chennai. Its placements are good but not more than the main campus.

Yes, Jaypee is a good option based on the number of companies that are visiting and the placement structure. SRM University is also good.

Prefer SRM University for MBA, there will be lots of chances for you in the placements process as number of companies are coming to SRM University. MEASI, you can keep as second option.

SRM is far more better than Manipal University.

Hello,
You have to pay the management quota fee which is hidden on the website but you have to pay 1 lakh more than the students who get admission through SRMJEEE that is Rs. 3,50,000 per year. So I suggest, you should join some other college.

I think SRM would cost around 20 lakhs.
