- Digit Span was skipped: its instructions state "This test is spoken aloud" — audio-administered with runtime-randomized digit sequences (3 subtests × 8 items × 2 trials, 2–9 digits, 60s response window). There is no fixed question bank to download.
- Answer keys: Analogies, Matrix Reasoning and Quantitative Knowledge embed
correct_keyin the client page (captured verbatim). Graph Mapping, Figure Weights, Visual Puzzles and Spatial Awareness are scored server-side; their answer keys are never sent to the browser, so those items are exported with answers pending. - Per-question time limits: AG 45s, MR 120s, GM 50s, FW 45s, VP 45s, SA 45s; QK varies per item (
secondsfield, default 60s). - VP (Visual Puzzles) uses checkboxes — exactly 3 options per item. MR choice numbering 1–5. QK
answer10field holds the question figure when present. - Training examples (with official answers) are included for MR, FW, VP, GM.
- Question sets are stable across page loads (verified 3 loads each); only presentation order varies.
