  • General studies

  • Opted local language or dialect to English

What they ask

Tier-I has 100 one-mark questions in an hour, 20 each from general awareness, quantitative aptitude, reasoning, English and general studies. The minimum Tier-I marks are 30 for unreserved and EWS, 28 for OBC and 25 for SC and ST. Tier-II asks you to translate a 500-word passage between your chosen local language and English in both directions, and you need 20 out of 50 to pass. Interview calls go out at five times the vacancies based on Tier-I marks, and the final list is made on Tier-I plus the interview.

How to prepare

  • Apply for the SIB whose listed language you can read and write comfortably, because Tier-II is a translation test in that language.
  • Translate a short news item from your local language into English and back every day, and time yourself against the one-hour limit.
  • Aim well above the Tier-I cut-off. Tier-I marks decide who gets an interview call and count in the final merit list.
  • Leave a question blank rather than guess wildly. A quarter mark goes for each wrong answer.
  • Use daily topic-wise practice quizzes on the free Improvam app for quantitative aptitude and reasoning.
