Hi Aspirant

Engineering is all about calculations so you need to be good at maths.

CS : Mathematics and computer related things 

ECE : Mathematics and Physics (Electric field,current electricity,communication)

CE : Mathematics and Physics (Mechanics,force,motion)

ME :Maths and Physics (Mechanics thermodynamics)

whichever suits you and you feel comfortable to study ,you can choose that.

hope this helps.

All the best.
