The hardest "Function Key" test on the market. Our AI decodes the hidden operators and predicts the final shape instantly.

| Test Name | Abstract Reasoning Ability Test (A-RAT 3R) |
| Time Limit | 90 Seconds per Question (Strict) |
| Format | Input Shape -> Function Keys -> Output Shape |
Unlike standard matrix tests, Hudson asks you to reverse-engineer what specific buttons do. "Button A makes it black," "Button B rotates it." It's deductive logic under extreme time pressure.
ReasonEra compares the "Original" and "Final" figures across multiple examples to deduce exactly what each function key does (e.g. Key 1 = Color Swap).
You have 90 seconds per question. Manually tracing 5 different function keys takes too long. Our AI solves the logic chain in under 2 seconds.
The operator changes the shape from Black to White or vice versa.
The operator rotates the shape 90° clockwise or counter-clockwise.
The operator changes the shape itself (e.g., Circle becomes Square).
The operator changes the size of the shape from Big to Small.
Logic diagrams are strict and unforgiving.
ReasonEra guarantees logical consistency.
The Abstract Reasoning Ability Test (A-RAT) by Hudson measures your ability to identify logical rules. Unlike typical matrix tests, it uses a 'Function Key' format where you must deduce the effect of specific buttons (operators) on shapes.
You must reverse-engineer the rule for each function key by comparing input and output shapes. ReasonEra automates this deductive process, identifying the rules instantly so you can select the correct answer.
