Before beginning with the answer, you should know that the score you have got is quite good and there are chances of you to get a seat in NIT Trichy. 

Here’s the process of NIT Trichy:

• Firstly, it is close to impossible to get a seat in CSE during the primary counseling of CCMT. 
• Moreover, the spot round can provide you with a seat for CSE Information Security in NIT Warangal. 
• Furthermore, after enrolling you have an option for internal sliding rounds in which there is a probability of getting a seat in the CSE branch. 
• If not that, then the college itself will release the number of seats on the website for the students who are still interested in enrolling.

On the other hand, there is a high possibility that NIT Warangal also has the same procedure but my brother wasn’t sure about it.
