SSC CGL Science: Real PYQ Questions (Physics, Chemistry & Biology)

Science in SSC CGL General Awareness spans Physics, Chemistry, and Biology basics — often testing precise factual recall rather than deep conceptual understanding. This article compiles real, verified Science questions extracted directly from official Tier 1 papers. 10 Real PYQ Questions Q1. Methane is a colourless, odourless, non-toxic but flammable gas. What is its common name? 1. Blue vitriol  2. Laughing gas  3. Marsh gas  4. Heating gas Show Answer 3. Marsh gas. Q2. Who is the only scientist in the world to have won the Nobel Prize in Chemistry twice? 1. Madame Curie  2. Roger D. Kornberg  3. Linus Carl Pauling  4. Frederick Sanger Show Answer 4. Frederick Sanger. He won in 1958 and again in 1980. (Marie Curie won two Nobel Prizes, but in different fields — Physics and Chemistry, not Chemistry twice.) Q3. Flying Officer _____ of the Indian Air Force created history by becoming the first Indian woman to fly a solo fighter flight in a Rus...

SSC CGL Tier 2 General Awareness: What's Different From Tier 1

SSC CGL Tier 2 General Awareness Strategy featured image

General Awareness in Tier 2 covers the same core subject areas as Tier 1 — but with meaningfully higher depth expected. This guide covers what actually changes in how you should prepare, rather than repeating the subject list you already know from Tier 1.

Same Subjects, Deeper Expectations

The core GA subject areas carry over directly from Tier 1: Polity, History, Geography, Economy, Science, and Current Affairs. See our Tier 1 General Awareness PYQ Breakdown for the subject-wise frequency data, which broadly holds for Tier 2 as well. What changes is the level of detail expected within each subject.

What Actually Gets Harder

SubjectTier 1 LevelTier 2 Level
PolityBasic constitutional facts, key articlesDeeper amendment history, landmark judgments, finer procedural details
HistoryMajor events, dates, key figuresCause-effect relationships, lesser-known movements and figures
GeographyBasic physical/political geographyEconomic geography, resource distribution, more specific regional detail
EconomyBasic terms and conceptsPolicy specifics, budget details, deeper institutional roles
ScienceGeneral scientific factsMore specific/technical scientific detail, recent developments
Current AffairsMajor recent eventsBroader coverage including less headline-dominant developments

Strategy 1: Read Beyond Headlines for Current Affairs

Tier 1-level current affairs prep (major headline events) isn't sufficient for Tier 2. Read full articles on significant developments, not just summaries — Tier 2 sometimes tests a specific detail from within a story, not just "did this happen."

Strategy 2: Connect Static GK to Current Events

Tier 2 increasingly tests where static facts intersect with current developments — for example, a question about the Finance Commission's constitutional role might be prompted by a recent Finance Commission recommendation in the news. Studying static GK and current affairs as connected, not separate, tracks pays off here.

Strategy 3: Don't Neglect "Boring" Institutional Detail

Questions about the specific composition, powers, and procedures of institutions (Finance Commission, CAG, RBI, Election Commission) appear more frequently and in more depth at Tier 2 than Tier 1. This is exactly the kind of dry, procedural content that's easy to skip in casual reading — but it's high-value for Tier 2 specifically.

Strategy 4: Build a Rolling Current Affairs Habit, Not a Cram Session

Given the breadth expected, a daily 20-30 minute habit of reading a reliable current affairs source consistently over months outperforms an intensive cram session close to the exam. GA breadth genuinely compounds over time in a way other sections don't.

What This Means for Your Study Time Allocation

If you're splitting prep time across all Tier 2 sections, GA deserves proportionally more daily (not weekly) attention than Reasoning or Quant, precisely because it's the one subject where consistent small daily exposure compounds meaningfully, versus Math and Reasoning which respond better to concentrated problem-solving sessions.

Frequently Asked Questions

Q1. Should I use different study material for Tier 2 GA versus Tier 1?
Not necessarily different material, but deeper engagement with the same core sources — reading full articles instead of summaries, and paying attention to institutional/procedural detail you might have skimmed for Tier 1.

Q2. How far back should my current affairs prep go for Tier 2?
Generally, the 12 months leading up to your exam date is the practical window worth focusing on, though landmark or particularly significant events from further back can still appear.

Q3. Is there a shortcut to Tier 2 GA prep?
Not really — GA rewards consistent breadth over shortcuts more than any other section. The closest thing to a shortcut is prioritizing institutional/procedural detail (Strategy 3 above), since this is commonly under-prepared by other aspirants.
