hi nithish,

you have top best options as:-

• Thiagarajar College of Engineering
• PSG College of Technology
• Anna University 
• Madras Institute of Technology
• Coimbatore Institute of Technology

all of them are AAAA rating which means it is an excellent college rating wise. but if you see the individual ranking of NIRF, Anna university #8 in between IITs which is a big thing. 

taking admission in anna university can be a bit hard so i would suggest to keep back up options ready. 

PSG College of Technology on 33

Thiagarajar College of Engineering being on 37

coimbatore institute on 51

in these 3 you can get easily. 

now course, you should opt for CSE or IT as it is the top branches with best facilities and faculties and placements are the best and top most in the college. 

hope it helped!

all the best!
