Not really. In fact, you can select 3 of your choices from the provided list. Generally, your first choice will be given. You asked about security and supervision. Fact is that depends upon state to state or even centre to centre. Let me explain to you further; suppose you select there centres say A, B, C and you are allotted centre A. JEE main people would select a college which has enough infrastructure to conduct the exam. Now the actual exam will be conducted by that college faculties only. At Most one person from CBSE would be there. In some cases those faculties don't even no the rules of the exam. In some places those people make things very difficult by unnecessary formalities. Such practices are more in down south. In any case security and supervision will be exemplary. Or in other wards very very strict. There will be two check points. Please take your Aadhar card or School identity card, the latest one. Don't ever feel like fooling or any mischief. there's no room for nonsense. Don't carry anything except what is being allowed.
All the best.

Step 1: Apply through JEE Mains website for B.Tech Arch before December 31.
step 2: Study and prepare well. NIT, Trichy is ranked number 1 and its very very tough to get admission into it.
Step 3 : You don't need to apply separately to get into NITT. That is the short form of NIT, Trichy.
step 4 : If you are a candidate from Tamil Nadu you are called home state. If you are a candidate from other state you are called other state. Other state candidate should have better ranks to get into NIT. For example if a home state boy gets admission with 3000 rank you need 1500 or so.
Step 4: Caste of a candidate plays a crucial role. If you are from general category then you should be in creamy layer.
Step 5 : Even if you get a good ranking still you ain't sure of your admission. Choice filling and preferential selection of colleges during counseling is very very vital. Its a game and you should play that wisely; there is no room for error. I would say take some experts help once counseling process started. Everything you have to do online.
Take my words because in 2017 June I admitted my son in this very very prestigious institution.
In case any further advise required do write to me.
