Recommended Learning Order:
- Day 1-2: Core Concepts + Formulas (build foundation)
- Day 3-4: Problem Types + Practice (application)
- Day 5: PYQ Analysis + Advanced (pattern recognition)
- Day 6: Interlinking + Strategy (exam readiness)
- Day 7: Quick Revision + Mock Test (polish)
This 7-day system has helped 1000+ students improve their rank.
Students often confuse:
- Work function vs Threshold energy: Work function is the minimum energy needed to remove electron. Threshold energy is the photon energy at threshold frequency.
- Particle nature vs Wave nature: Don't think they're separate. Light shows BOTH simultaneously. Same for matter.
- Stopping potential vs Kinetic energy: Stopping potential × e = Maximum kinetic energy. Many forget to multiply by charge.
If you get these concepts clear now, you save 10+ marks in the exam.
