There were two sections in the DRDO paper(CS)

There were 50 questions in this section, questions were from simple reasoning or I can say that reasoning was very easy, there were verbal and non-verbal type questions. but there were also questions from English and G.K. although it was not mentioned in prospect that English and G.K questions will come,

Some G.K.questions were easy like–Tank Developed by DRDO(Arjun).
PRITHVI is what kind of missile(surface to surface).
Mahatma Gandhi during breaking ognsalt rule move up to(Dandi)…etc..
