Hey there

Deciding branch in engineering is ofcourse very confusing due to which most of engineers study things which they don't like. But if you want to choose branch of your interest then just think in peace what you like example if you are good at and interested at coding then go for CSE in case you are interested in electricity then go for electrical, if you are interested in mechanics then mechanical, if you are interested in knowing about metals their extraction then metallurgy etc. Just research on internet first about the branch you want to choose and first be sure about the pros and cons then choose.

Good luck
