Details of Descriptive Examination

The written examination will be of the descriptive type, consisting of two papers of 300 marks each, to be conducted in two sessions of the duration of three hours each.
The syllabus of the Descriptive Examination(downloadable from the RAC website) is similar to the Engineering Services Examination (Main) in the relevant discipline conducted by the Union Public Service Commission (UPSC).
The Descriptive Examination will be administered in a paper-based format.
Tentatively, the Descriptive Examination will be conducted at DRDO centres in seven cities (Bengaluru, Chennai, Delhi, Hyderabad, Kanpur, Kolkata, and Pune) as well as at other common centres, if the need arises.
Candidates are required to indicate their first and second preference of examination centre in the online application form among the listed centres.
The Descriptive Examination is likely to be held in October 2020
