VIT Vellore. The placements are hands-down best! It's a bit costlier but still worth the cost. I am a student here in VIT and I can say it's good.

Yes. The Campus life is good here in VIT Vellore. Its campus is huge and the events and festivals make our lives fun. I am a student of VIT for 1.5 years and I have thoroughly enjoyed the campus life. I would suggest, you join student clubs and chapters and it would be fun to spend your time here.

Yes, you can get admission. But admission is not based solely on 12th marks. You have to get good score in the entrance exam as well.
All the best.

That is a very specific subject and I am not sure if a course exists for solely that topic. Automobile Engineering, Electronics Engineering or Instrumentation Engineering are some courses that deal with this topic.

B.Sc Agriculture or Bachelor of Science in Agriculture is an undergraduate Agriculture Science and Technology course. The duration of this course is four years. Candidate must have passed class 12th with PCB with at least 50% to 60%. As per my knowledge, you are not eligible to get admission good government college to pursue B.Sc. Agriculture in Tamil Nadu after scoring 140 cutoff marks in +2 exam, so my suggestion to you is that you can apply for admission in that college which accept your score.

After May, the admission process will begin for B.Tech in St. Joseph's College, Chennai.

Some of the good colleges that offer B.Sc Information and Technology in Chennai, are-
1. SRM
2. Wisdom School of Management
3. Loyola
4. Mahatma Gandhi University

Hindustan University is one of the best university in Chennai, and it is very good for B.Tech in automobile engineering, as it is known for this. So, I think you should take admission in this university.
