hello saif uzzama

I hope you are doing good . As per your query , I would like to know you that changing of branch is not easy as it sound and it id depend of many terms and conditons. Every year only 4-5 students get the chance to changer their branch after 1st year . Firslty you need to have very very high cgpa atleast more than 9.2 and secondly upgrading to cse branch is very difficult because all seats are already full if someone left from the college then you can upgrade on that vacancy whereas upgrading to ECE branch is somewhat easy

Hope you found this answer helpful. Good luck for your future
