Default Re: IES exam subjects to concentrate more

As you want to get some information about the IES examination, so here I want to inform you that it is not a simple examination.

So you have to prepare all subjects.

You are a B.Tech or B.E Graduate, so you have to concentrate on all subjects of your branch.

IES Exam Subjects

General English / General Studies

Civil Engineering

Mechanical Engineering

Electrical Engineering

Electronics and Telecommunication Engineering
