Hi, Hope you are doing well!

There is an option for branch change in NIT Warangal. But if you are joining the Institute into a stream you have no interest in, then its more like a luck game. Changing your branch solely depends on your CGPA by the end of first year. But once you are allotted an other branch you cannot refuse it. So be careful while filling your preferences. This happens based on your performance at the end of first year (CGPA). Everyone with a CGPA above 8 is eligible to apply for it. Finally, based on the preference order of branches that you fill, you’ll get a branch; just the way your JEE counselling happened.

Generally students with CGPA 9.3 and above opt for CSE and ECE and the ones with 9–9.3 get electrical , mechanical and civil. The rest (min CGPA is 8 though)go for chemical , biotechnology and metallurgy. I think each branch would accept around 3–5 people to get in and people with higher CGPA are given preference .

So, yes you can change your branch from Biotech to CSE/ECE only if you have filled CSE/ECE in your preference list and have the required CGPA by the end of your 1st year.
