Colleges in Tamil Nadu - Other

B.Tech in CS in not available from distance education in this university. My opinion on that is also that distance education is not beneficial for B.Tech courses.

Dear Athira,
You can surely pursue the course. You need to initially start with the procedure. It could be registration, payment and other details. I am sharing with you the link of the course to know how you will be enrolling, your subject, fee structure, study center and other details regarding to the course. I hope you reach heights with your dancing skills.

Hello Mr Mahendran,
Your son's profile is indeed prolific. In addition admissions in Tamil Nadu are based on only marks of 12th, hence I think with such good academics, your son is bound to get admission in his desired branch and desired college.
Best wishes to you.
