General Science

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

General Science in the CUET UG General Test pulls Class 10–12 NCERT concepts from Physics, Chemistry, and Biology into roughly 15–18 mixed MCQs worth about 3% of the paper. The section rewards conceptual clarity over calculation depth, so the high-yield items are definitions, formulas, and the small set of facts examiners recycle year after year.

AreaMust-know fact
UnitsForce in newton (N), not kg; 1 N = 1 kg·m/s²
ElectricityOhm’s law: V = IR, series R adds, parallel 1/R adds
LightConcave mirror forms real, inverted images for objects beyond F
ChemistrypH < 7 acidic, pH = 7 neutral, pH > 7 basic
BiologyProducers (green plants) start every food chain

Tip: Questions usually arrive as one-liners (“Unit of resistance is…”) or quick reasoning (“Litmus in NaOH turns…”). Read the stem, pick the NCERT-aligned fact, move on.

🟡 Standard — Regular Study (2d–2mo)

Standard content for students with a few days to months.

Scope and Format

The General Test domain on CUET UG blends General Science with other GK streams. Science-specific items test NCERT fundamentals of physics, chemistry, and biology, frequently in a single paragraph or table-comparison stem. Roughly 15–18 questions appear, no negative marking risk if attempted with NCERT clarity.

Core Formulas to Memorise

FormulaMeaning
F = m·aNewton’s second law; F in N, m in kg, a in m/s²
W = F·dWork in joule = force × displacement along force direction
P = V·IElectrical power in watt = voltage × current
V = I·ROhm’s law; V in volt, I in ampere, R in ohm
c = f·λWave relation; c = 3 × 10⁸ m/s
pH = −log[H⁺]Negative log of H⁺ concentration in mol/L

Physics Cluster

Mechanics leans on Newton’s three laws: inertia (1st), F = ma (2nd), action-reaction (3rd). Work-energy problems use W = F·d cosθ, and the simple-machine idea of mechanical advantage = load/effort recurs. Light covers reflection (θᵢ = θᵣ), refraction (Snell’s law: n₁ sin θ₁ = n₂ sin θ₂), and the human-eye defects myopia (distant blur, corrected by concave lens) and hypermetropia (near blur, convex lens).

Chemistry Cluster

Master the pH scale (0–14), common indicators (litmus, phenolphthalein, methyl orange), and the difference between strong vs weak acids. Know periodic-table trends: metallic character increases down a group and decreases across a period.

Biology Cluster

Cell theory (Schleiden, Schwann, Virchow), plant vs animal cell differences, and photosynthesis equation 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ are staple items. Mendel’s monohybrid cross F₂ ratio 3:1 and dihybrid 9:3:3:1 appear almost every year.

Edge Cases and Mechanism-Level Traps

  • Mass vs weight: Mass (kg) measures matter; weight (N = mg) measures gravitational pull. Examiners exploit this in numericals by giving g = 9.8 m/s² and asking “weight of a 10 kg body” — answer 98 N, not 10 kg.
  • Series vs parallel resistors: Series: R_total = R₁ + R₂ + … (same current, voltage divides). Parallel: 1/R_total = 1/R₁ + 1/R₂ + … (same voltage, current divides). Mixing these formulas is the single most common mistake.
  • Litmus logic: Blue litmus stays blue in acid and turns red in base. Red litmus turns blue in base. Memorise both directions.
  • Concave vs convex ambiguity: Mirrors and lenses invert the image behaviour. A convex mirror always gives a virtual, erect, diminished image regardless of object distance; a concave lens behaves similarly.

Connection to Adjacent Topics

General Science overlaps heavily with the General Knowledge and Quantitative Aptitude clusters on CUET UG. Units and dimensional analysis tie into numerical-ability SI-prefix questions; the photosynthesis equation links to the Environmental Science stream via carbon cycling.

Practice Prompts

  1. A wire of 4 Ω and 6 Ω are connected in parallel across a 12 V battery. Find the current through the 6 Ω resistor. (Hint: parallel voltage = 12 V across each, I = V/R.)
  2. In a monohybrid cross between two heterozygotes (Tt × Tt), what is the phenotypic ratio of tall to short in the F₂ generation?

Strategy: In the actual test, mark NCERT-confident science items first, then revisit any calculation you spent more than 60 seconds on. Don’t over-engineer — most General Science MCQs answer in one line.
