How to prepare Sudoku
- Pick one topic and read its concept summary and formula list before attempting anything.
- Attempt all the questions on paper with a timer before you reveal any answer.
- Read every explanation, including for questions you answered correctly — the shortcut matters more than the result.
- Re-attempt the topic after two days; accuracy under time pressure is what the exam actually measures.
- Finish with a mixed-topic timed aptitude test to simulate real exam conditions.
