SRM is quite a good pvt university. Mostly famous for its engineering stream. But, you can rely on its other schools and departments. Moreover in private universities, Manipal is the best for OT. SRM is also good.
Still, you can try for National Institute of Empowerment of persons with multiple disabilities if you wish to study in govt institution in Chennai. For that, you need to give entrance conducted by three institutions run by Central Government.

No, you cannot get admission now, as the dates are already gone long back. Right now, students who were admitted this year are already writing their first semester exams and will be done within next 10_15 days.

As both colleges are good enough. But, if you want to choose one of them, I would recommend you to choose VITEEE, as your first preference, because it has good faculty members, good facilities, well infrastructure etc. And, last but not the least good placement.

JB, SRM Guntur (Andhra Pradesh) is a new campus of SRM University and first batch will pass out in year 2021. While SRM Chennai campus is an old campus and established in 1985, and have very good record of placement. So, you should go with SRM Chennai campus.
