I've got my PSO exam scheduled in 3 weeks and I've been splitting prep between the physical fitness standards and the written cognitive battery. The physical piece I'm in good shape for – I've been running 4 days a week and my timed events are all above the minimums. The written part is what I'm more uncertain about because the practice materials I've found vary a lot in how they describe what's actually tested.
From what I can tell the cognitive section hits reading comprehension, basic math and data interpretation, situational judgment, and some memory/observation components. The situational judgment questions concern me most because the “best response” framing is subjective and I've been burned on those in other exams by overthinking what the test writers considered the correct priority. My reading comprehension is strong – scoring 85%+ on those practice sets – but the math I'm around 72% and the judgment scenarios I genuinely can't tell how I'm doing.
The agency I'm testing with uses a contracted testing vendor and the specific platform matters because the interface affects how you manage time on the memory and observation items. Does anyone know if there's a way to find out which vendor administers the exam beforehand so I can practice on a similar interface?
The memory and observation section is usually timed very tightly and you see information once before it disappears. Practice by studying a scene or image for 90 seconds, then immediately answering questions without looking back. Your brain needs to build the habit of active encoding, not passive viewing.
Some agencies post their approved testing vendors on the job listing or the HR portal. Worth checking the original job posting for any mention of a vendor name or testing platform. Even a general search for the agency name plus PSO written exam format sometimes surfaces useful candidate experience threads.
Your 72% math score is fine for most PSO exams I've seen – the calculations are not advanced, mostly percentages, unit conversions, and basic data table reading. One solid review session on those specific types should get you to 80%+ and that's probably enough margin for the math section.
For situational judgment the consistent principle across most law enforcement and protective service exams is: de-escalation first, chain of command second, documentation third. When in doubt, the answer that involves the most conservative use of authority and the most communication is usually right. Memorizing that priority order helped me stop second-guessing.
