See every colleges has its own advantages and disadvantages, it's own uniqueness, and it's own pros and cons and the reviews will differ from people to people. If I were at your place, giving my personal review I would've chosen SRM University for btech over all the other colleges. The reason for this being, even though infrastructure and curriculum wise Presidency University or LPU might be better, but SRM has got some great placement and some great companies offer jobs here in this college for campus placements. The teaching staff is also good and cooperative.

Thank you.
