Aspiring quants
Practise the investigation and communication layer that textbooks rarely cover.
Free launch beta · no signup
Your first day on the quant desk starts with a broken number.
Investigate realistic pricing, risk and model-validation incidents. Inspect the evidence, run controlled tests and defend a diagnosis that can survive review.

How it works
No flashcards. No answer theatre.
You are scored on the quality of your investigation, not on guessing a hidden keyword.
-
01
Read the desk
Start with the same incomplete brief, conflicting numbers and stakeholder messages a desk quant receives.
-
02
Spend your evidence budget
Inspect artefacts and choose tests deliberately. Decisive experiments beat noisy, expensive reruns.
-
03
Defend the diagnosis
Submit the root cause, remediation and controls. Receive a transparent scorecard and worked debrief.
Transparent assessment
A score you can audit.
Every point comes from a visible rubric: diagnosis, remediation, evidence, preventive controls and investigation efficiency. The simulator does not pretend that an opaque AI opinion is ground truth.
- Deterministic scoring for repeatable practice
- Worked causal explanation after submission
- Progress stored only on your current device

Desk ready · strong causal diagnosis
Built for the gap
Between knowing a model and supporting one.
Early-career practitioners
Build a repeatable approach to P&L breaks, calibration failures and numerical noise.
Interview candidates
Develop stronger desk-scenario answers by working through evidence instead of memorising scripts.
Questions
Before you enter the desk.
Is this a trading system or model certification tool?+
No. It is an educational simulation built from fictional cases. It does not connect to markets, execute trades, certify models or replace independent professional review.
Do I need an account or payment method?+
No. The launch beta is immediately usable without an account or card. Completed scores are saved in your browser on this device.
Is there one correct investigation path?+
No. You may run any available test. Scoring rewards decisive evidence and penalises only inefficient or unsafe choices; the debrief explains the causal chain.

Briefing

YOUR MANDATE
Read the brief, then inspect the available evidence.
EVIDENCE ROOM
Inspect what the desk already knows.
Some artefacts unlock only after you run the relevant investigation test.
Opening an artefact is free. Running a test spends investigation budget.
INVESTIGATION QUEUE
Choose the next discriminating test.
Every test consumes budget. You may submit a diagnosis at any time, but unsupported conclusions score poorly.
RESULT STREAM
0 tests run
No results yet. Select a test above to begin the investigation.
Run evidence-producing tests before diagnosing.
FINAL HANDOFF
Defend your diagnosis.
Your submission is graded against a visible rubric. Select only factors and controls that materially belong in the causal chain.
