Dear,

In my college, I noticed many girls taking the admission into UG Computer Science Engineering, Electronics and Communications Engineering and Chemical Engineering.

1. CSE: Students with high thinking capacity usually take this because they need to think a lot to get the logic of the programs at the right time. They don't need to do much work physically I think.
2. ECE: Students who are well versed in physics and having interest in electronics systems take this branch. They must stay up-to-date on recent advancements on technology.
3. Chemical: Of course, they need to be interested in chemistry.Besides that ,they must be fascinated by the experiments which chemical students usually do in their laboratories.

Keeping all the above matter aside, Interest is the most important and fundamental thing required to take any branch of engineering. The branch, the student shows interest should be the branch that he/she should take.

Hope this helps!
