    ⚡ Physics — Key Chapters & Formulas

    ๐Ÿ”น Chapter 10: Light — Reflection & Refraction

    ๐Ÿงฎ Important Formulas

    • ๐Ÿ“ Mirror Formula: 1/v + 1/u = 1/f
    • ๐Ÿ“ Lens Formula: 1/v - 1/u = 1/f
    • ๐Ÿ“ Magnification (mirror): m = -v/u = h'/h
    • ๐Ÿ“ Magnification (lens): m = v/u = h'/h
    • ๐Ÿ“ Power of Lens: P = 1/f (in metres) — Unit: Diopter (D)
    • ๐Ÿ“ Refractive Index: n = sin i / sin r (Snell's Law)
    • ๐Ÿ“ Sign Convention: Distances measured from pole/optical centre; direction of incident light = positive
    ๐Ÿ’ก Memory Trick

    "Mirror: +v+u, Lens: -v+u" — Mirror formula has both positive, lens formula has v negative. For magnification, mirror has negative sign, lens has positive. Remember this and you'll never make sign errors!

    ๐Ÿ”น Chapter 12: Electricity

    ⚡ Electricity Formulas

    • ๐Ÿ“ Ohm's Law: V = IR
    • ๐Ÿ“ Resistivity: R = ฯl/A (ฯ = resistivity, l = length, A = area)
    • ๐Ÿ“ Series Combination: R_total = R₁ + R₂ + R₃
    • ๐Ÿ“ Parallel Combination: 1/R_total = 1/R₁ + 1/R₂ + 1/R₃
    • ๐Ÿ“ Electric Power: P = VI = I²R = V²/R
    • ๐Ÿ“ Electric Energy: E = P × t (Unit: kWh = 1 unit)
    • ๐Ÿ“ Heat Produced: H = I²Rt (Joule's Law of Heating)
    ⚠️ Common Mistake

    Students often confuse series and parallel combinations. Remember: In series, current is same, voltage divides. In parallel, voltage is same, current divides. This is the most asked concept in board exams!

    ๐Ÿงช Chemistry — Key Chapters & Concepts

    ๐Ÿ”น Chapter 1: Chemical Reactions & Equations

    1
    Types of reactions: Combination, Decomposition, Displacement, Double displacement, Redox, Precipitation
    2
    Balancing equations: Number of atoms of each element must be equal on both sides
    3
    Exothermic vs Endothermic: Exothermic releases heat (ฮ”H < 0), Endothermic absorbs heat (ฮ”H > 0)
    4
    Corrosion & Rancidity: Corrosion = oxidation of metals; Rancidity = oxidation of fats/oils. Prevention: antioxidants, refrigeration, airtight containers

    ๐Ÿ”น Chapter 2: Acids, Bases & Salts

    AcidsBases
    Property
    TasteSourBitter
    pH< 7> 7
    LitmusBlue → RedRed → Blue
    ExamplesHCl, H₂SO₄, CH₃COOHNaOH, KOH, Ca(OH)₂
    Reaction with metalsProduces H₂ gasSome react (Al, Zn)
    ๐Ÿ“Œ Important Salts to Remember

    Plaster of Paris: CaSO₄·½H₂O (used in casts, toys)
    Baking Soda: NaHCO₃ (used in baking, antacids)
    Washing Soda: Na₂CO₃·10H₂O (used in cleaning)
    Bleaching Powder: CaOCl₂ (used in water treatment)

    ๐Ÿ”น Chapter 4: Carbon & its Compounds

    1
    Electronic configuration of Carbon: 2, 4 — needs 4 electrons to complete octet → forms covalent bonds
    2
    Versatile nature of Carbon: Tetravalency + Catenation (ability to form long chains) → millions of compounds
    3
    Allotropes: Diamond (hardest), Graphite (conductor), Fullerenes (C₆₀)
    4
    Homologous series: Family of compounds with same functional group, similar chemical properties, differ by -CH₂ unit
    5
    Functional groups: -OH (alcohol), -CHO (aldehyde), -COOH (carboxylic acid), -CO- (ketone)

    ๐Ÿงฌ Biology — Key Chapters & Concepts

    ๐Ÿ”น Chapter 6: Life Processes

    Life ProcessDefinitionKey Organs/Structures
    NutritionObtaining & utilising foodStomach, small intestine, villi
    RespirationBreakdown of glucose to release energyLungs, alveoli, mitochondria
    TransportationMoving substances throughout bodyHeart, blood vessels, xylem, phloem
    ExcretionRemoval of waste productsKidneys, nephrons, ureters
    ๐Ÿ’ก Memory Trick

    "Nutrition, Respiration, Transportation, Excretion" — remember as "NRTE" or "Never Run To Eat". These are the 4 life processes every student must know!

    ๐Ÿ”น Chapter 9: Heredity & Evolution

    1
    Mendel's Laws: Law of Dominance, Law of Segregation, Law of Independent Assortment
    2
    Monohybrid cross: TT × tt → F₁: Tt (all tall) → F₂: 3 tall : 1 dwarf (3:1 ratio)
    3
    Dihybrid cross: F₂ ratio = 9:3:3:1 (round yellow : round green : wrinkled yellow : wrinkled green)
    4
    Sex determination: XX = female, XY = male. Father determines sex of child (contributes X or Y)
    5
    Evolution: Gradual development of new species from existing ones. Evidences: fossils, homologous organs, analogous organs, embryology

    ❌ Common Mistakes Students Make in Board Exams

    Forgetting sign convention in mirror/lens numericals. Correct: Always apply sign convention FIRST. Object distance (u) is always negative. Focal length: concave mirror = -ve, convex mirror = +ve.
    Writing "respiration = breathing". Correct: Breathing is just inhalation/exhalation. Respiration is the cellular process of breaking down glucose to release energy (C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy).
    Confusing series and parallel circuits. Correct: Series = same current, voltage divides, R_total = R₁+R₂. Parallel = same voltage, current divides, 1/R_total = 1/R₁+1/R₂.
    Not balancing chemical equations. Correct: Always check that number of atoms of each element is equal on both sides. Example: 2H₂ + O₂ → 2H₂O (balanced), not H₂ + O₂ → H₂O.
    Writing "diamond conducts electricity". Correct: Diamond is an insulator (no free electrons). Graphite conducts electricity due to free delocalised electrons between layers.
    Confusing homologous and analogous organs. Correct: Homologous = same structure, different function (forelimbs of human, whale, bat). Analogous = different structure, same function (wings of bird & insect).

    ๐ŸŽฏ Board Exam Tips & Strategy

    ๐Ÿ“ How to Score 90+ in Class 10 Science

    1. NCERT is Bible: 95% questions come directly from NCERT. Read every line, diagram, and activity.
    2. Practice diagrams: 5-10 marks are diagram-based. Practice labeling diagrams of heart, brain, flower, etc.
    3. Numerical practice: Physics numericals (light, electricity) carry 8-10 marks. Practice at least 30 numericals.
    4. Previous year papers: Solve last 5 years' papers. You'll notice pattern and repeated questions.
    5. Time management: 3 hours for 80 marks = 2.25 minutes per mark. Don't spend too much time on one question.

    ⚠️ Last-Minute Revision Strategy

    1 week before exam: Revise all formulas, definitions, and diagrams. Don't read full chapters.
    1 day before exam: Only look at formula sheets and important diagrams. Don't study anything new.
    Exam day morning: Glance through formula sheet once. Stay calm and confident.
