Lab
PRACTICE ISN’T WIRED UP YET.
This is meant to become a space to try item formats without spending your one official attempt. Today, there is no practice-mode endpoint on the API — every assessment session created by POST /v1/assessment/sessions is a real, entitlement-consuming attempt. There is no free-to-retry "Lab" mode on the backend yet, so this page stops short of offering one.
What the official assessment involves
- Costs $10 / £10 / €10, consumed the moment your session starts.
- One attempt per eligibility window.
- Timed per item, with a server-enforced hard limit.
- Item types: numeric sequences, visual-spatial rotation, logical relations, digit-span memory.
