FSOSD is an online exam.

Before scheduling FSOSD, confirm the current question count, time limit and passing standard with Linux Foundation and FINOS, since these details are updated from time to time. Knowing them in advance lets you set a realistic pace in practice sessions and avoid surprises on exam day.

Preparation for FSOSD works best when it mirrors the exam outline. Allow roughly 6 weeks, giving each major area its own block: begin with Open Source in Financial Services, continue with FINOS Projects and Community; Open Source Licensing and Compliance; and Contributing to Open Source Projects, and finish with Security and Supply Chain Practices; and Collaboration Tools and Governance. Write short notes for each area in your own words and revisit them regularly. In the last week, switch from reading to timed mixed practice so the exam pace feels familiar.

In the final weeks before FSOSD, take timed practice tests and review every explanation, including for questions you answered correctly. Notice which keywords in a question point to a specific service or setting.

For FSOSD, set up a free tier account, sandbox or local lab and repeat the core tasks from each objective until they feel routine. Pair this with documentation reading for limits, defaults and best practices, since exam questions often test those details.
