Auto sets the level from your recent results: up when you are acing it, down when it is too hard.
How to play
- 1Read the four values in the dataset.
- 2Answer the question: a total, a difference, or which is highest or lowest.
- 3Select the correct option.
- 4Or switch to Chart check: one chart stays on screen and you judge a stream of True, False or Cannot-tell statements against the clock.
Tactics under the clock
- Read the question or statement first, then hunt only for the figures it needs.
- In Chart check, if the chart does not contain the answer, choose Cannot tell rather than guessing False.
- Keep a steady rhythm and never stall on one item; commit and move on.
See a worked example
A table gives take-off run 430 m at 1,800 kg and 590 m at 2,200 kg, and asks for 2,000 kg. The skill is interpolation, and the method is a fraction, not a formula. Ask how far along you are between the rows: 2,000 sits halfway between 1,800 and 2,200. Then take the same fraction of the change in the answer column: the run changes by 160 m, half of that is 80 m, so 430 + 80 = 510 m. Read the question one more time before you answer, because these items alternate between asking for the value and asking for the CHANGE in the value, and 80 will be sitting there as an option. The trap that costs most marks is reading the nearer row straight off the table: an answer that exactly equals a printed number is nearly always the one you were meant to interpolate past.
Selection tests and the flight deck both demand quick, accurate reading of tables and figures. Scan a short dataset and answer totals, differences and which entry is highest or lowest, without losing time.

What this test measures
This measures reading and reasoning with tables and figures: pulling the right number from a busy dataset and combining values correctly. Charts and tables fill the performance and planning manuals, so fast, accurate extraction matters.
How to improve your score
- Read the question first, then go to the table knowing exactly which cell you need.
- Check the column and row headings and the units before you take a value.
- Do the arithmetic on the extracted numbers carefully, the lookup is only half the task.

Read the question before the table
Find out what is being asked, then look only for the figures you need. Absorbing the whole dataset first wastes time you do not have and tempts you into using the wrong row.Totals, gaps and extremes
Almost every item is a sum, a difference, or a highest or lowest. Once you spot which, the answer is one or two clean operations away. Check you are comparing like with like, the same column and the same units.Chart check: when the answer is Cannot tell
In Chart check mode the trap is a plausible statement the chart cannot actually settle: a claim about a category that is not plotted, a change over time when only one period is shown, or a per-unit rate when only totals are given. Those are Cannot tell, not False. Answer False only when the chart shows it is false.
