SRM Institute of Science and Technology Kattankulathur Chennai Answered Questions

It depends on the branch you want.
With 32K rank, you will not get CSE, ECE and mechanical but you might get EEE and other branches in the main campus. Else, you can also get CSE/ECE in other branches of SRM. Trend changes every year, might not be the same this year. So, think properly before you commit to something.
Cheers.

Yes, you can get admission in SRM University. If you scored high in SRM JEE test, then you can get scholarships. Also, with such a high percentage, you can get admission in any college you desire. The cut off for SRM is 70 % above and SRM JEE test rank.

I would say a big no. Never go behind the brand name of a college but see the curriculum they have and what they are actually offering to students, the placement and package for the degree you want to pursue there. Don't trust college posters, banners or other marketing materials.
Try to get in touch with the students out their in the institution you are willing to pursue your studies via the social network, or have a visit to the campus and interact with them. All the best.

We can differentiate one from other on the basis of following factors.
1. Faculty: Faculty at Amrita and VIT are reasonably good but more number of Ph.Ds are at Amrita I guess. Faculty at Amrita are friendly compared to faculty at other colleges.
2. Discipline and Values: In this Amrita stands at top giving importance to discipline and values. Along with education for living one can learn education for life at VIT only. But VIT university sometimes fails in this( this is from the information of my friends)
3. Labs: Labs are good at Amrita, VIT and Manipal University.
4. Infrastructure: Infrastructure at Amrita is good compared to rest. Vellore also has good infrastructure and hotels they say. But being in Amrita is homely.
5. Placements: Placements percentage at VIT stands top among these but the placement percentages of others is also not very low. They are almost comparable. But the companies come to hire, sometimes take the students for IT jobs (even the non-computer science student). Students placed in core (mechanical, electrical and electronics ) are low, mostly they will be placed in TCS, Infosys, Wipro, Tech Mahindra etc. Based on the above details you have to decide which suits you.
