Set selection comes first
DILR questions come in sets, with each set built around a scenario, table or graph. Every set contributes several questions, so abandoning one midway is costly. The first five minutes of the sectional should go into reading and ranking sets by perceived difficulty.
Set types to practise
- Arrangements and selections with multiple conditions
- Games, tournaments and rankings
- Tables, bar and line charts, and caselets with calculation
- Networks, routes and scheduling
Learning from each mock
After every mock, redo the sets you skipped or abandoned without a clock, noting how long they genuinely take. You will often find that a set you rejected was solvable and that your rejection came from unfamiliar wording. Over several tests, your ability to judge solvability improves, which is the actual skill being tested. Data-focused drills such as data interpretation practice build the underlying fluency.
