Hello aspirant, 

If you have got admission in tier one colleges i. e., IITs and NITs then you can prefer your interested course though it maybe civil or mechanical too. But if you have chances of getting into local engineering colleges then I would suggest you that CSE, ECE, IT  have top priority and then EEE. If colleges are top then civil and mechanical is OK. Hope you understood. 

All the very best for your bright future!!
