 The medium of examination is English.
 In IES, there will be a deduction of onethird of the mark allotted for each question for every wrong answer attempted.
IES Syllabus 2018
 Indian Engineering Services examination is conducted in three stages.
 The first two stages are written examinations.
 Stage 1 consists of 2 Papers namely General Studies & Engineering Aptitude (Paper 1) and Engineering Discipline (Civil/ Mechanical/ Electrical/ Electronics & Telecommunication Engineering).
 The questions in Paper 1 are based on Current issues, Basic Engineering Aptitude, Engineering Mathematics and Numerical Analysis etc.
 The questions in Paper 2 are based on the chosen engineering discipline.
 Stage 2 also consists of 2 Papers, both the papers are engineering discipline specific.
