Paper analysis
Snapshot of GATE IN 2020
GATE IN 2020 gave one full paper. The official key lists 30 MCQ, 35 NAT, so 54% of the paper is typed-answer (NAT) questions, which carry no negative marking.
Of the 55 Instrumentation Engineering questions, 25 are worth 1 mark and 30 worth 2 marks; 25 of the 2-mark questions are NAT.
Against GATE IN 2019, MCQs moved by -12 and NATs by +12.
GATE 2020 was organised by IIT Delhi; the original files were published on the organising site and are linked below through the Internet Archive.
What this paper stresses
- IN has an unusually high share of NAT questions in several years, so numerical accuracy and the printed rounding range matter more than option elimination.
- Control systems, signals and measurements are cross-linked: one transfer-function method often serves questions in all three.
- General Aptitude is 10 questions and 15 marks, easy to rush.
What to extract before you move on
- NAT vs MCQ miss counts.
- GA topics you guessed versus knew.
- A personal subject-weight table for Instrumentation Engineering from this sitting: Engineering Mathematics, Electrical Circuits, Signals and Systems 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.
