16. Solved revision set and final exam plan
Free study material · concepts, shortcuts & solved questions
The final stage is mixed retrieval. Do not practise only by river system; real papers mix geography, projects, environment and current affairs. Use the answer explanations to identify whether the error was a location error, a name-chain error, a tributary error, a project error or an overconfident current-status claim.
Exam lens A good book supports preparation; selection still requires full-syllabus study, previous-paper analysis, timed tests and repeated revision. |
