Diagnostic practice

100 questions published across 10 sections. Every question is written for this skill specifically — no universal or borrowed bank is substituted. Answers are checked on this device only, and the result is an educational practice band for that exercise, never a clinical, diagnostic, or IQ-style score.

Choose a section

This bank has 10 themed sections and 100 questions in total, ordered so the earlier sections are the gentler ones. Sit a single section, or work through the whole bank in one go. Nothing here is timed — the minutes are only a guide.

Section 1: Reading single-step flow diagrams

Each item describes one operation box — apply its rule exactly as stated.

1. A flow diagram shows a single box labelled 'Add 4'. The number 9 enters the box. What number comes out?
2. A box labelled 'Double' receives the number 7. What is the output?
3. A box labelled 'Reverse' receives the letter sequence P-Q-R. What sequence comes out?
4. A box labelled 'Remove the last item' receives the list: apple, pear, plum. What list comes out?
5. A box labelled 'Rotate 90° clockwise' receives a printed arrow pointing straight up. Which way does the arrow point on the way out?
6. A box labelled 'Swap the first and last symbols' receives the sequence ★ ● ▲ ■. What comes out?
7. A box labelled 'Halve' receives the number 26. What is the output?
8. A box labelled 'Toggle shading' turns white figures black and black figures white without changing the shape. A white triangle enters. What comes out?
9. A box labelled 'Repeat the whole sequence twice' receives the sequence A-B. What comes out?
10. A box labelled 'Subtract 6' receives the number 6. What is the output?
