⚡ Physics — Key Chapters & Formulas
๐น Chapter 10: Light — Reflection & Refraction
๐งฎ Important Formulas
- ๐ Mirror Formula:
1/v + 1/u = 1/f - ๐ Lens Formula:
1/v - 1/u = 1/f - ๐ Magnification (mirror):
m = -v/u = h'/h - ๐ Magnification (lens):
m = v/u = h'/h - ๐ Power of Lens:
P = 1/f (in metres)— Unit: Diopter (D) - ๐ Refractive Index:
n = sin i / sin r(Snell's Law) - ๐ Sign Convention: Distances measured from pole/optical centre; direction of incident light = positive
"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!
๐น Chapter 12: Electricity
⚡ Electricity Formulas
- ๐ Ohm's Law:
V = IR - ๐ Resistivity:
R = ฯl/A(ฯ = resistivity, l = length, A = area) - ๐ Series Combination:
R_total = R₁ + R₂ + R₃ - ๐ Parallel Combination:
1/R_total = 1/R₁ + 1/R₂ + 1/R₃ - ๐ Electric Power:
P = VI = I²R = V²/R - ๐ Electric Energy:
E = P × t(Unit: kWh = 1 unit) - ๐ Heat Produced:
H = I²Rt(Joule's Law of Heating)
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!
๐งช Chemistry — Key Chapters & Concepts
๐น Chapter 1: Chemical Reactions & Equations
๐น Chapter 2: Acids, Bases & Salts
| Property | AcidsBases||
|---|---|---|
| Taste | Sour | Bitter |
| pH | < 7 | > 7 |
| Litmus | Blue → Red | Red → Blue |
| Examples | HCl, H₂SO₄, CH₃COOH | NaOH, KOH, Ca(OH)₂ |
| Reaction with metals | Produces H₂ gas | Some react (Al, Zn) |
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)
๐น Chapter 4: Carbon & its Compounds
๐งฌ Biology — Key Chapters & Concepts
๐น Chapter 6: Life Processes
| Life Process | Definition | Key Organs/Structures |
|---|---|---|
| Nutrition | Obtaining & utilising food | Stomach, small intestine, villi |
| Respiration | Breakdown of glucose to release energy | Lungs, alveoli, mitochondria |
| Transportation | Moving substances throughout body | Heart, blood vessels, xylem, phloem |
| Excretion | Removal of waste products | Kidneys, nephrons, ureters |
"Nutrition, Respiration, Transportation, Excretion" — remember as "NRTE" or "Never Run To Eat". These are the 4 life processes every student must know!
๐น Chapter 9: Heredity & Evolution

❌ Common Mistakes Students Make in Board Exams
๐ฏ Board Exam Tips & Strategy
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.
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.
