IES Exam Electrical Pattern Stage-1: (Preliminary/Phase-1)

Preliminary Examination has consisted with two papers (Paper-1 & Paper-2). The Engineering Services (Preliminary/Phase-I) exam will consist of two objective type (multiple choice) question papers and carry a maximum of 500 marks (Paper 1 - 200 marks and Paper II - 300 marks). If you qualify the Preliminary/Phase-I Examination, then you will be eligible for the Main/Phase-II Examination. The number of candidates appearing in the Main/Phase-II examination will be approximately six to seven times the total estimated number of vacancies to be filled through this examination.

Exams Duration:

Paper-1: 2 hours (120 minutes) Morning Shift

Paper-2: 3 hours (180 minutes) Afternoon Shift

Name of Paper


[Paper-1] General Studies and Engineering Aptitude Paper


[Paper-2] Engineering Discipline [Electrical Engineering]


Total [Paper-1 + Paper-2]


Negative Marking: There will be penalty (Negative Marking) for wrong answers marked by a candidate in the objective type question papers.

1.      There are four alternative for the answers to every question. For each question for which a wrong answer has been given by the candidate, one-third (1/3rd) of the marks assigned to that question will be deducted as penalty.

2.     If a candidate gives more than one answer, it will be treated as a wrong answer even if one of the given answers happen to be correct and there will be same penalty as above for that question.

3.     If a question is left blank i.e. no answer is given by the candidate, there will be no penalty for that question.

IES Exam Electrical Pattern Stage-2: (Main/Phase-2)

Mains Examination has consisted with two papers (Paper-1 & Paper-2). Only candidates who clear the IES Preliminary exam will be able to appear in the IES Mains exam. The Engineering Services (Main/Phase-II) examination will consist of two conventional type papers in engineering discipline with a duration of three hours and a maximum of 600 marks (300 marks in each paper).

Exams Duration:

Paper-1: 3 hours (180 minutes) Morning Shift

Paper-2: 3 hours (180 minutes) Afternoon Shift

Name of Paper


[Paper-1] Engineering Discipline-specific Paper-1 [Electrical Engineering]


[Paper-2] Engineering Discipline-specific Paper-2 [Electrical Engineering]
