Each cognitive faculty is measured as accuracy (0–100%), then weighted into a final composite score out of 100.
25%STEERING — sustained attention & motor precision. Time-weighted by distance from the centerline (centre = full credit, lane edge = zero).
20%ATTENTION — reactive selective attention. Of the hazards that were in your path (centre half of the lane), the share you avoided. Edge-of-lane hazards you never needed to dodge don't inflate the score.
20%MEMORY — working memory. Correct memory checkpoints ÷ total.
25%APTITUDE — processing speed & numerical fluency. Correct ÷ total, plus speed bonus for answers under 5 s.
10%GLYPH PRECISION — fine-motor / divided-attention bonus. Glyphs driven through ÷ glyphs encountered.
