Design Aptitude Part A: Objective Reasoning for Designers
Part A rewards a trained eye more than memorised facts. Expect questions on visualisation and mental rotation (folding nets into cubes, mirror images, embedded figures), spatial and proportional reasoning (scaling, ratios, symmetry), observation and recall of shown material, basic colour and design vocabulary (hue, value, saturation; primary/secondary/tertiary; warm vs cool), elements and principles of design (line, shape, form, texture, space, balance, rhythm, emphasis, contrast, proportion, unity), and environmental and everyday-product awareness (materials, function, ergonomics).
Traps are consistent. In rotation items, a cube net can be folded two ways - check which face is opposite rather than which is adjacent. Mirror questions flip left-right but not top-bottom; water-reflection flips vertically. In proportion questions, candidates average the wrong pair or forget that area scales as the square of the length ratio. Colour questions confuse value (lightness) with saturation (purity). Vocabulary questions often pair a principle with its near-opposite (rhythm vs repetition, contrast vs harmony).
Worked rule of thumb: the cube-net "opposite faces" check
For a cross-shaped net, faces separated by exactly one square in a straight line are opposite. So in a row of four squares, square 1 is opposite square 3 and square 2 is opposite square 4. Eliminate any answer option that shows two opposite faces adjacent - that single check usually removes two options before you rotate anything.
Pace yourself: Part A is speed-scored, so mark uncertain items and return. Sketching tiny diagrams on rough paper is faster and safer than rotating shapes in your head.
