About OA Practice Desk

OA Practice Desk is a free, open practice bank for company online assessments (OAs). It collects 2213 questions from 62 company patterns, each with an answer key and a written explanation.

How it works

Every question has its own page, so you can link to it, bookmark it or find it from search. Section pages add a practice mode with a question palette, bookmarks and progress tracking.

There is no account and no server-side profile. Your answers, notes and bookmarks are stored in your own browser's local storage, and you can export them to a file from the progress panel on the home page.

Where the questions come from

Questions are reconstructed from publicly shared assessment reports and cleaned up by hand: prompts are normalised, options de-duplicated, and answers re-derived so the explanation matches the key. They are practice material, not leaked papers, and company names describe the assessment pattern a question follows.

Corrections

If a question or an answer key looks wrong, it probably is - the bank is large and reconstructed. Corrections are welcome through the public issue tracker.
