PYQ Pattern Analyzer — What CBSE Repeats Every Year
The Secret: CBSE Doesn't Repeat Questions, It Repeats PATTERNS
2019: "Calculate the resistance when V=12V, I=2A"
2020: "Find the current when V=6V, R=3Ω"
2021: "A circuit has R=5Ω. If V=10V, find I and P"
2022: "Two resistors 3Ω and 6Ω in parallel. Find equivalent R"
→ PATTERN: Ohm's law + circuit calculation appears EVERY year as 3M or 5M

How to Use PYQ Patterns
1. If a pattern appears EVERY year → practice 10+ variations of it
2. If a pattern appears 4/5 years → practice 5+ variations
3. Start with GUARANTEED 5M patterns — highest marks-per-hour
4. Use Oswaal PYQ section — questions are already sorted by year
5. Time yourself — if you can't solve a pattern in target time, drill more
