Hello Aspirant,
See on such ST rank it would be very difficult to get any good college like NITs/IIITs/GFTI on such ST rank because closing ST ranks of last year were like :-
@Other state quota
Dr. B R Ambedkar National Institute of Technology, Jalandhar - Industrial and Production Engineering (3317)
National Institute of Technology Agartala - Production Engineering (3445)
@Home state quota
National Institute of Technology Agartala - Chemical Engineering (28232)
National Institute of Technology Calicut - Electrical and Electronics Engineering (35617)
Dr. B R Ambedkar National Institute of Technology, Jalandhar - Computer Science and Engineering (27,269)
You can check out previous year's cut-offs from the official website of JOSAA as given below :-
https://josaa.nic.in/Result/Result/currentorcr.aspx
According to the ST rank mentioned in the query you have no chance to get any of the NITs/IIITs/CFTIs/GFTIs until and unless you deserves Home state quota for them , so I would recommend you to either go for private colleges or you can prepare for further attempts of JEE-Main and to help you in your preparation we have some resources which you can access from the link given below :-

Note that the above prediction is made on the basis of latest cut-offs available on official website of JOSAA or CSAB and the cut-offs are bound to change every year depending upon various factors such as the number of candidates appearing in an examination, the number of candidates qualifying an examination, difficulty level of the paper, and so on.
