How the UWSA 1 Step 1 score calculator converts your misses
The UWSA 1 score conversion for Step 1 is one rule: score = round(294.38 − 1.109 × wrong answers) over 160 questions. The UWSA 1 Step 1 score calculator applies it flat.
No curve, no per-system weighting, no adjustment for where the misses fell. Every miss costs the same 1.109 points in the UWSA 1 Step 1 score calculator.
Nine questions are worth roughly ten points at 40 misses and at 120 alike, which makes the UWSA 1 Step 1 score calculator easy to run backwards.
Pick a target, subtract it from 294.38, divide by 1.109, and you have your allowance. The UWSA 1 Step 1 score calculator does that arithmetic for you.
A single linear fit is all the circulated UWorld data supports, so the UWSA 1 Step 1 score calculator claims no curve it cannot justify.
