Trading OA Simulation
A timed two-section assessment: a mental math sprint at real screening pace, then probability and expected-value questions under the clock.
Assessment rules
2 sections, ~40-60 minutes total. Section clocks run continuously; there is no pause. A fixed 30-second break separates sections.
Forward-only: you can skip a question, but you cannot return to it.
The mental-math section (where present) uses the firm preset's penalty scoring: wrong answers cost points, skips do not. Other objective-question sections score +1 per correct answer. Coding attempts are timed but not scored.
No feedback during the assessment. Afterwards, the report reviews each objectively scored question against the correct answer, with links to full explanations. Coding problems reopen in the editor and remain marked as attempted, not scored.

What this is modeled on
Modeled on candidate-reported OA structures (e.g. Optiver's ~8 min (reported) arithmetic assessment; SIG's 20 or 60 min in reported variants quantitative assessment). Role-generic: not affiliated with or endorsed by any firm; real formats vary by role, office, and year. Last reviewed 2026-08-08.
Free accounts and visitors get a shortened sample at the full format's pace; a completed sample result can be kept with a free account. Premium unlocks the full format with saved reports.
