Yes. The eight-question quiz on this page is free, with no account or payment required. It shows your score and answer explanations after you finish. Full timed practice tests are separate paid products.
There is no single public score we can use to promise eligibility for every role. Discuss your Job Opportunities Report with your recruiter. A Service Prep quiz score is a practice result, not an ADF eligibility decision.
The ADF guide revised in June 2025 states three attempts with at least six months between attempts. Further attempts require valid reasons accepted by the ADF. Confirm your own eligibility and timing with your recruiter.
No. ADF Careers says the JOA assesses natural abilities, does not require study, and provides official example questions. Commercial practice is optional and is not endorsed by the ADF. Our tests offer an additional structured practice experience, without a score guarantee.
