Semiconductor Electronics: Materials, Devices and Simple Circuits contributed 23 of the 387 NEET Physics questions between 2020 and 2026 (Re-NEET 2026 included). That is 5.9% of the subject and makes it the #3 chapter out of 30 by weightage — roughly 2.9 questions per paper, peaking at 4 in NEET 2024.
Of the 23 questions tagged for difficulty, 17% were easy, 70% medium and 13% hard — mostly medium-level questions that reward practice beyond one-line facts.
Its weight has stayed fairly steady: 2.3 questions per paper across NEET 2025, NEET 2026 and Re-NEET 2026, against 3 in 2020–2022.
The single most-tested topic is Digital Electronics and Logic Gates (Logic Gates) — 4 questions across 3 papers.
11 topics tagged under Semiconductor Electronics: Materials, Devices and Simple Circuits. Numbers show how many questions each topic had in each paper; E / M / H are the easy, medium and hard counts.
