Dear Gnana,

i will answer these question in a qeue:

1. How about B.arch in NIT trichy?

B. Arch at NIT TRICHY is among the top in India. Please go for it .

2. Is that course is worth enough for 5 years?

B .arch of nit trichy is good enough ,i will prefer it over B .arch of IIT roorkee and IIT kgp because basically iit does not take any specific exam for Barch except that AAT(architecture aptitude test) so the top cream of Barch is selected through JEE Mains B .arch only.

3. what will be my salary if i completed my b.arch at trichy NIT?

Don't look for future of doing any course from any college see whether you have interest in that particular field or not and give your 100% and i have seen students getting good package applying off campus so Chase your passion. there are numerous examples of students from less known colleges achieving  success based on interest.

hope you got your answer.
