PS practice questions - frequently asked questions

Plain answers about how PS Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real PS exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The PS exam spans 6 domains: Planning and Evaluation (25% of the exam); Prevention Education and Service Delivery (15% of the exam); Communication (15% of the exam); Community Organization (15% of the exam); Public Policy and Environmental Change (11% of the exam); Professional Growth and Responsibility (19% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Planning and Evaluation 25%; Professional Growth and Responsibility 19%; Prevention Education and Service Delivery 15%; Communication 15%; Community Organization 15%; Public Policy and Environmental Change 11%.

The PS exam has 150 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
