“I did GS for Prelims, so GK is covered.” IFoS General Knowledge is a separate written paper with its own syllabus, depth and question style: it is written, not ticked. Your Prelims reading is the raw material; what’s missing is knowing which dimensions a question wants, how much to write, and where the examiner expects the answer to go. The printed syllabus is one paragraph, but 13 years of papers show the real boundary runs into environment, economy, agriculture and S&T.
Built and taught by Neil Sir: HCS 2021, Rank 93.
Three layers, in order.
Layer 1 · Syllabus Parsing
8 videos, 6h 06m: read the syllabus as a cheat sheet, subject by subject.
Layer 2 · PYQ Mapping
6 videos, 10h 58m: every past question taken apart into what it acknowledges, asserts and implies, then rebuilt as an answer plan.
Layer 3 · Model answers & handouts
Model answers 2019–2023 with a walkthrough, the 156-page S&T mind-map handouts, and 7 years of GK papers in full.
24 compulsory sub-answers in 180 minutes

No. IFoS General Knowledge is a separate written paper with its own syllabus, depth and style. Your Prelims reading is the raw information; this module adds what doesn’t carry over, which dimensions a question wants, how much to write, and where the examiner expects the answer to go.
18 videos (17h 48m) in three layers (Syllabus Parsing, PYQ Mapping, and Model Answers) plus 14 documents including 156-page Science & Technology mind-map handouts and GK papers from 2019 to 2025.
6 questions, each in 4 parts: 24 compulsory sub-answers in 180 minutes, about seven minutes each. Parts (a) and (b) are 15 marks / 200 words; (c) and (d) are 10 marks / 125 words. There’s no internal choice, so coverage matters more than depth on any one topic.
The printed syllabus is one paragraph, but 13 years of papers run well past it into environment, economy, agriculture and S&T. PYQ Mapping shows you the paper’s real boundary, so you stop over-reading topics that have never been asked in depth.
Under 18 hours of video, plus the handouts: a week or two of evenings at your own pace.
Yes. All six PYQ-mapping documents come with the videos, so you can revise the whole mapping without sitting through the hours again.
Neil Sir (HCS 2021, Rank 93). Model answers run 2019–2023 and the GK papers go up to 2025.
Yes: instant access, nothing drip-fed, 1-year validity.

Big thanks: I cleared IFoS this year after failing last year’s pre. It was down to Pre Sherlocking.
I cleared the IFoS cutoff in 2024 prelims, in my very first attempt: I scored 100.35, exactly hitting the IFoS cutoff, only because of you.
I was able to clear CSE 2024 and Forest prelims. Analysis of PYQs from the Sherlocking module helped me realise what to read, what to skip, and at what depth.
