Colleges in Tiruchirappalli

You're only aiming for NIT Trichy? Why not IITs or other private institutions? How can you expect results without working hard for it?
Another thing: are you okay with getting into NITT, but into chemical or metallurgy, and get a 4 Lacs job? NIT fees are going to be hiked to almost 2 Lacs per year without hostel. Is it okay with you?
If you have the passion for those subjects and don't mind the salary, then it's fine. But I get this question from juniors who ask this question based on some placement surveys, so I don't know how you are any different. Mind you, only CS EC & EE get good salaries for core jobs.
Placements are in bad shape, teachers are very bad atleast for the first 2 years and trichy's weather is extreme and will drain out all your energy if you aren't motivated enough. Students don't learn anything in comparison to the other local colleges in trichy. Think multiple times before joining this place.
Moreover, you can crack JEE Mains with good marks within one year to get into NIT trichy if you work hard in 12th standard now.

Hi Karthik
No it maybe difficult for you to get admission in NIT Trichy as cut off is quite high in NITs but it also depends on your interest which stream you are going to choose,if for example you want CSE then it may be difficult for you to get seat but if you choose stream such as biotechnology or textile then there may be chance for you to take admission but don't worry as there is second chance in which you can improve your scores. And talking about the marks about which no such information is available but you can know your rank by using rank predictor which is also available on shiksha site and more details about your marks and rank will be clear once second paper is conductedas both the results would be combined.
Good luck.
