You already know the EPPP isn't a knowledge test. It's a stamina test that happens to be about knowledge. And if you're retaking it, you know exactly how it feels to study something for weeks and still get surprised on exam day. I built EPPP Study as a licensed clinical psychologist. I wanted the tool I wish I'd had: something that tells you what you actually don't know, not just what you haven't reviewed yet. PRACTICE - Full 225-question EPPP simulations and a free 71-question diagnostic - Study Mode explains every answer the moment you pick it - Ask the built-in AI tutor why an answer is right and how to spot similar questions PRIORITIZE - Your results become a domain-by-domain breakdown - Get told exactly which domains to focus on, ranked STUDY - Readable lessons across all EPPP domains - Read-along audio, follow-up questions to an AI teacher, and a quiz at the end of every topic RECOVER - Test anxiety is part of this exam. A dedicated space to decompress, with a supportive chat when studying gets heavy - Educational support, not therapy or medical care SYNCS WITH THE WEBSITE Your account works on thepsychology.ai too. Exams taken on your phone show up on the web, and the other way around. Pro subscription unlocks full practice exams. New accounts start with a free week. Subscriptions auto-renew until canceled in your App Store settings. Terms: https://www.thepsychology.ai/terms Privacy: https://www.thepsychology.ai/privacy
