The DRDO test, known as the Scientist Entry Test (SET), is held once a year as a paper-based exam. Section A and Section B are the two sections of SET. The duration of the paper is estimated to be 3 hours (or 180 minutes, to be exact). Both parts feature negative markings, however, the amounts vary: Section A deducts 1 mark for each incorrect answer, while Section B deducts 0.5 marks.
