Where GATE EC's marks have come from, 2018–2026: every subject, paper by paper

This is a count, not a forecast: how many marks GATE EC's seven keyed papers — 2018, 2020, 2022, 2023, 2024, 2025 and 2026 — gave to each published study subject, for a GATE EC candidate working out the subject component of a study plan. The GATE 2027 Information Brochure fixes the paper at 65 questions and 100 marks, with General Aptitude a constant 15 marks that sit outside the subject syllabus; the remaining 85 marks — Engineering Mathematics plus the core subjects — are the subject component this post counts (GATE 2027 Information Brochure, printed page 4).

Where GATE EC's 85 subject marks have come from, paper by paper

The table lines up all seven papers side by side. Engineering Mathematics's row swings from 9 marks in 2026 to 16 in 2022 — a 7-mark range it shares with Signals and Systems (7 to 14) — because IAE's tags run 9 to 16 marks per paper against the brochure's fixed 13 marks for the subject: the tags are IAE's reading of each question, not the paper's own section boundaries. Analog Electronics and Digital Electronics track closely in most years (0–1 marks apart), though they diverged more in 2025 (13 marks against 9). The row for marks 'not yet filed under a published subject' runs 7 to 12 marks a paper: these are marks on questions that no published subject's classifier has filed — this includes the sections the study library has not covered yet, and can include any question from a covered section that no classifier took. This post does not say what those marks were made of.

GATE EC subjects in order of average marks per paper

By average marks per paper, the order runs Engineering Mathematics at 12.7, then Analog Electronics at 10.6, Digital Electronics at 10.4, and Signals and Systems at 9.6. Control Systems and Electronic Devices tie at 8.7 each — the same average to one decimal place, so the counts put them level rather than one ahead of the other. Electromagnetics follows at 7.6, and Networks (Electric Circuits) is last at 6.7. A plan that follows the marks would take Engineering Mathematics, Analog Electronics and Digital Electronics first, Signals and Systems next, then treat Control Systems and Electronic Devices as equal in weight, followed by Electromagnetics, and leave Networks for last on this measure — every one of these subjects appeared in all seven papers, so this is about the marks each has carried on average, not about how often a subject showed up. General Aptitude sits outside this order: a fixed 15 marks, separate from the 85-mark subject component ranked here.

The GATE EC syllabus, section by section, against the study library

Section 7 of the official syllabus, Communications, is not yet covered by a published study subject. These marks are part of what the first table's 'not yet filed' row counts — that row also includes any question from a covered section that no classifier took, so it is not made up of Communications marks alone. Every other syllabus section maps to a subject already in the library, including Section 2, Networks, Signals and Systems, which corresponds to two published subjects: Networks (Electric Circuits) and Signals and Systems.
