Before you start
- Select an answer, then confirm it. Confirmed answers cannot be changed. Use A–E or 1–5, or select on screen.
- Each knowledge section has its own practice clock. Time continues if you hide or leave the page. Take breaks between sections. Questions adapt using our editorial difficulty levels.
- Full-practice answers and performance feedback appear only at the end. Trait familiarization has no score; your preferences are never saved.
- Use a desktop or laptop, keyboard, pointing device, and stereo headphones. Check the controls and left/right audio before an attempt begins.
- Your unfinished sitting stays in this browser for this account. Use one practice tab at a time. Complete every stage to save the final review.
Independent ASTB-E preparation. Our questions, adaptive selection, section clocks and performance exercises are practice settings, not an official Navy test or score prediction. Follow the instructions for your actual test.
