Paper analysis
Snapshot of GATE PI 2021
GATE PI 2021 is hosted below as the official question paper (with the official answer key inside the same PDF). Question-type counts were not tabulated for this paper.
GATE 2021 was organised by IIT Bombay; the original files were published on the organising site and are linked below through the Internet Archive.
What this paper stresses
- PI mixes mechanical-style numericals with management-style ones (inventory, queueing, forecasting), so build separate formula sheets for the two kinds.
- NAT answers in operations research and inventory depend on rounding rules; use the range printed in the key.
- General Aptitude is 10 questions and 15 marks, easy to rush.
What to extract before you move on
- NAT vs MCQ miss counts. MSQ misses separately, since one wrong option loses the whole question.
- GA topics you guessed versus knew.
- A personal subject-weight table for Production and Industrial Engineering from this sitting: Engineering Mathematics, General Engineering, Manufacturing Processes and the rest.
- Every question where your answer was right but your time on it was not.
Analyst note: Mark by the numbering in the paper you downloaded.
How to sit GATE PI 2021
- Download the paper and its answer key from this page. Do not open the key yet.
- Sit the full paper in three hours, one sitting: 10 GA questions and 55 Production and Industrial Engineering questions. Re-key NAT answers before you stop.
- Mark it with the official key: MCQ by option, NAT by the range in the key. Give an MSQ mark only when the whole option set matches. Apply negative marks on MCQs only.
- Fill the error log the same day: section, subject, and miss type (concept, silly, time or misread).
- Next session, repair only the logged items, then pick another year from the list below.
