General English and General Knowledge together carry 600 of the 1,400 written marks in IFoS Mains — and unlike the CSE language papers, both are fully counted in your final rank. Here is the verified paper structure, the official syllabus, the previous year papers, and the Sherlocking modules built for exactly these two papers.
The two compulsory papers are worth 600 marks — about 43% of the 1,400-mark written examination. The official UPSC notification is explicit: marks obtained in the Main Examination, written part as well as interview, determine final ranking. Even the tie-breaking rule ranks candidates by their aggregate in the two compulsory papers plus the Personality Test.
Common myth: “English is only qualifying”
Several popular preparation websites claim the IFoS General English paper is qualifying-only and that its marks are not added to your total. This is wrong. The UPSC notification counts all six written papers — including General English — in the 1,400-mark written total that determines your rank. (The 2025 notification did carry a screening note for the GK paper — scripts were evaluated only for candidates clearing a Commission-set minimum in Paper II — and that note no longer appears in the 2026 notification.)
The strategic reality, as Neil Sir explains in the orientation below: the hardest stage of IFoS is the Prelims. Candidates who clear it often under-prepare the compulsory papers because they assume the optionals will carry them — while good study material for exactly these two papers barely exists. That gap is what the Sherlocking IFoS modules are built to close.

The official syllabus for both papers is barely a paragraph long — so we verified the real structure from the actual UPSC question papers of 2024 and 2025. Every question was compulsory in both papers, both years.
UPSC does not prescribe this split in the syllabus — it is our reading of the official 2024 and 2025 papers (sources below), and it can change in a future year.
Both compulsory papers in one PYQ-centred module: every previous year question from 2013–2025 discussed, model answers for the 2019–2023 GK papers, S&T handouts, one evaluated GK mock FLT, and Telegram doubt support. 35 video lectures + 46 files, 1-year validity.
Every lecture maps to a question of the actual paper — nothing generic, nothing padded. Grammar is taught through logic rather than rote rules, with reference repositories for the parts that genuinely need revision (idioms, homophones). Every English PYQ from 2013 to 2025 is discussed.
| Lecture | Duration | Paper question it targets |
|---|---|---|
| Essay (Parts 1–6) | 3 hr 25 min | Q1 — Essay of 800–1,000 words (100 marks) |
| Formal Letter Writing + PYQ doc | 44 min | Q2 — Short compositions (25 marks) |
| Report Writing + PYQ doc | 55 min | Q2 — Newspaper report (25 marks) |
| Précis Writing | 1 hr 12 min | Q3 — Précis to one-third length (50 marks) |
| Comprehension — Basics & PYQs + doc | 1 hr 4 min | Q4 — Reading comprehension (50 marks) |
| Sentence Correction | 1 hr 6 min | Q5(a) — Grammar corrections |
| Adjective & Noun Formation | 21 min | Q5 — Word-form sub-parts |
| Rewrite as Directed | 31 min | Q5 — Rewrite-as-directed sub-part |
| Idioms + reference doc | 16 min | Q5 — Idiomatic-expression sub-part |
| Homophones | 19 min | Q5 — Confusable word pairs |
Plus 14 supporting documents for the essay module and PYQ-format docs for letter, report and comprehension. Available standalone as the IFoS English Module (16 lectures + 29 files, ₹7,510).
The GK paper is not CSE General Studies — it rewards breadth, structure and speed across 24 compulsory answers in three hours. The module teaches you to use the UPSC syllabus itself as a cheat sheet to generate dimensions, then drills the actual papers:
Art & Culture · Modern & Post-Independence History · Polity · Geography · Environment · Disaster Management · Economy · Science & Technology — learn to use the UPSC syllabus as a cheat sheet to generate dimensions for any question.
History · Polity · Economy · International Relations · Science & Tech · Environment & Geography — every previous year question from 2013 to 2025 mapped to the syllabus, with a PDF companion per subject.
Full model answers for five years of actual GK papers, written within word limits (not copy-pasted from Google), plus a how-to-use lecture.
Dedicated handouts for the topics students struggle with the most, so you do not need a separate current-affairs magazine.
One complementary full-length test written about two weeks before the exam, evaluated so you know your real level.
Available standalone as the IFoS GK Module (18 lectures + 16 files, ₹7,510).

“I would like to sincerely thank you for your invaluable guidance and support during my preparation… it made a significant difference in my journey.”
“Sherlocking helped me streamline my preparation and focus on what truly matters. The strategy was clear, practical, and effective.”
What does a winning written score look like? UPSC’s official marks disclosures show IFoS 2023 topper Ritvika Pandey scored 822/1,400 in the written examination, and IFoS 2024 topper Kanika Anabh scored 790/1,400 — while the official IFoS 2025 cutoff sheet put the General-category written cutoff at 675/1,400 (subject to a minimum of 5% marks in each paper). With 600 of those 1,400 marks sitting in English and GK, the compulsory papers are where the cutoff-to-topper gap is built. We compiled paper-wise English and GK scores from 40+ real candidate marksheets on the IFoS toppers’ marks page.

Yes. Unlike UPSC CSE, where the language papers are only qualifying, in the Indian Forest Service (Main) Examination both Paper I (General English, 300 marks) and Paper II (General Knowledge, 300 marks) are fully counted. The official UPSC notification states that marks obtained in the Main Examination — written part as well as interview — determine final ranking, and the first tie-breaking criterion is the two compulsory papers plus the Personality Test. Some popular websites wrongly claim English is qualifying-only; the notification says otherwise.
IFoS Mains has 6 conventional (essay-type) written papers of 3 hours each: Paper I General English (300 marks), Paper II General Knowledge (300 marks), and two optional subjects with two papers each (200 marks per paper). The written total is 1,400 marks, followed by a Personality Test (interview) of 300 marks, making a grand total of 1,700. All papers are set in and must be answered in English.
In recent years (verified from the actual 2024 and 2025 UPSC papers), the 300-mark General English paper had five compulsory questions: an essay of 800–1,000 words (100 marks), two short compositions such as a formal letter or proverb expansion plus a newspaper report (25 + 25 marks), a précis reducing a ~500-word passage to one-third length (50 marks), a reading-comprehension passage with five questions (50 marks), and a grammar-and-usage question in six sub-parts covering error correction, word forms, idioms, rewrite-as-directed and confusable word pairs (50 marks). UPSC does not prescribe this split in the syllabus, so it can vary.
In the 2024 and 2025 papers, the 300-mark General Knowledge paper had 6 questions, each with 4 compulsory parts — 24 answers in all, with no choice. Parts (a) and (b) carry 15 marks each with a 200-word limit; parts (c) and (d) carry 10 marks each with a 125-word limit. Questions are directive and descriptive (Discuss, Critically examine, Comment, Analyze) across history, art and culture, polity, economy, geography, environment, agriculture and forestry, and science and technology, including current events.
The Sherlocking IFoS Combined Module covers both compulsory papers: an English module (essay in six parts, formal letter, report writing, comprehension, précis, sentence correction, idioms, homophones, noun/adjective formation and rewrite-as-directed, with PYQ-based documents) and a GK module (subject-wise syllabus parsing in 8 lectures, subject-wise PYQ mapping, model answers for the 2019–2023 GK papers, Science & Technology handouts, and one complementary GK mock full-length test with evaluation). It discusses every previous year question from 2013 to 2025, includes 35 video lectures and 46 files, has 1-year validity and Telegram doubt support.
Yes. Besides the combined module, UnlockIAS offers a standalone Sherlocking IFoS English Module (16 video lectures + 29 files) and a standalone Sherlocking IFoS GK Module (18 video lectures + 16 files), each priced at ₹7,510 with 1-year validity. The combined module is priced lower than buying both separately.
The two papers are deliberately compact to prepare compared to optionals — but they cannot be done in two days. The Sherlocking modules are time-optimised: the English module is about 10 hours of video plus reference documents, and the GK module about 18 lectures built around syllabus parsing and PYQ mapping, designed for the roughly five-month window between the Prelims result and IFoS Mains (which begins 22 November in 2026).
The Indian Forest Service (Main) Examination 2026 commences on 22 November 2026 and spans 7 days, per the official UPSC calendar. The screening test through Civil Services (Preliminary) Examination 2026 was held on 24 May 2026, and its result for IFoS Mains qualifiers was declared on 15 June 2026 — 1,046 candidates were shortlisted against approximately 80 vacancies.
UPSC publishes the official IFoS Mains General English and General Knowledge question papers as PDFs on upsc.gov.in — the last three years on the Previous Question Papers page and 2016–2022 in its Archives section. UnlockIAS maintains a year-wise index with direct official links on its IFoS previous year papers page, and the Sherlocking IFoS modules discuss every PYQ from 2013 to 2025 with model answers for GK (2019–2023).
One of the very few dedicated programs in India built only for the IFoS compulsory papers — PYQ-centred, time-optimised, with model answers and evaluated practice. Combined module ₹12,009 (list ₹15,009) or standalone modules at ₹7,510 each; current coupons are shown on the checkout page.
