How to Use GAT-B / BET Previous Year Papers?
- Do not guess blind in GAT-B Section A. With +1 and −0.5, a blind guess among four options loses 0.125 marks on average, and ruling out one option only breaks even. Guess there only when you can rule out two options.
- Pick your Section B questions fast. In GAT-B you answer 60 of 100 and in BET 50 of 150. Practise scanning the section once and choosing your questions in the first 10 minutes.
- Pace the attempts, not the paper. GAT-B gives 3 hours for 120 attempted questions, 90 seconds each. BET gives 3 hours for 100, under 2 minutes each, but its Section B questions are longer.
- Score 2021 first. The 2021 papers mark the answer under every question, so start with them to learn the marking. The 2022 to 2024 papers have no key, so check doubtful answers from your textbooks.
- Plan for May 2027. About six and a half months remain. If you are taking both, solve a GAT-B and a BET paper on the same day to get used to two 3-hour shifts.
