I don't think many universities offer the biomedical science courses in Tamil Nadu. As per my knowledge, only two colleges offer this course. They are:
1) Bharath University, Selaiyur, Chennai
2) Sri Ramachandra University, Porur, Chennai

Bharath University, also known as Bharath Institute of Higher Education and Research(BIHER) and Bharath Institute of Science and Technology(BIST), is a deemed University and an Indian institute of higher education in Chennai, the capital of Tamil Nadu, India. It is approved by the University Grants Commission (UGC) and is accredited by the National Assessment and Accreditation Council (NAAC) with the highest grade of A.
The official website of Bharath university is www.bharathuniv.ac.in

Hello Abinesh,
I think both are the better to study, but Sastra University is better than St. Joseph College. Sastra University has better placements, education and rankings.
So, if you don't get Sastra University, then opt for St .Joseph College, Chennai.

Yes, Vel Tech University, Chennai is a good college for pursuing B.Tech degree. The faculty and the quality of education is good. And, the placements are also better in Vel Tech. If you don't get any other better college than this, then you can go for Vel Tech University, Chennai.

Sorry to say but you will not get admission in an architecture college with this score as a score of 90+ is considered in NATA to get admission in B.Arch in various Govt. colleges. Moreover, for NITs and other government colleges, you need a score of 300+ in JEE Mains paper-2. All the best!
