What makes a concept reliable
- It was asked every year, not just in a spike.
- Even its lowest year had a real number of questions.
- It sits inside a chapter that is itself stable.
How to practise them
- Pick three concepts from the list per week.
- Solve every previous-year question on them.
- Write a one-line rule and one trap for each.

Frequently Asked Questions
What does "asked in all five years" mean?
The concept had at least one question in each of 2022, 2023, 2024, 2025 and 2026.
Is a consistent concept guaranteed next year?
No. Consistency raises the odds but guarantees nothing.
