TNEA Scores

Among ECE and CSE, deciding which one is better depends on the person's interest. Both are equally good. If you love coding and stuff, then it'll be better to choose CSE, and if you love more of circuits and robotics, then choose ECE. Between ECE and CSE, there are higher chances of CSE getting higher pay packages. But don't get disheartened. As for campus placements, mainly IT companies visit and they pool both from ECE and CSE background depending only on your abilities. Again, both the streams will give you a lot of scope for higher studies!
In ECE, you have an additional advantage- ESE (Engineering Service Examination) covers only 4 streams and ECE is among them. You can join some core companies for ECE, which will fetch you a high salary.

MIT offers only 8 courses if I am not wrong where as PSG offers 18 different courses now including Robotics. Aeronautical is good in MIT where as PSG doesn't have the course. Location also matters when you choose a college. I had around 15 guys in my batch ( BE Production) 20082012 from Chennai when they had the option to take any course from MIT and a few available courses from CEG, even then they preferred PSG to CEG/MIT. Guys who want to do research kind of courses they could take biotech and Biomed. One of my friends who studied biotech in PSG is now doing some kind of research abroad. It all comes down to the person who studies (subjective). Automobile/ Metallurgy has good scope in PSG. For CSE, conglomerates like Deloitte, Goldman Sachs come for placements. Campus life is good at PSG.

Final choice should be yours. But here are some points that can guide you. SSN is a self-financing college under Anna University and so the Semester exam corrections ***! Even if you perform well, you will not get a grade as expected by you in the University examinations. There are good students who fail in any exam too and may or may not clear that subject after revaluations. The grades can affect your future job prospects whereas in MIT, which is Anna University, the same subject lecturer or any other professor from the same department will evaluate the papers. And the evaluations are mostly clear and predictive. MIT doesn't lack in infrastructure. It may not be as good-looking and lavish as SSN but still you have everything (like good labs) to learn engineering without any hiccups. In MIT, the quality of teaching may not be good but as a student, you will be well exposed to a dynamic environment where you can self-learn with seniors/peers. Last but the most important, hundreds of companies visit Anna University for placements. Salary packages from top companies have exceeded 20lpa for students. Placements are the best in this college compared to other departments.
