The TEAS is a gate, not a guess. Study one question at a time with calm, focused practice - A&P review that finally sticks, weak-area drilling, and a pass-probability score that tells you you're ready before test day.
Free to start · no credit card · $39 one-time for the full plan (90 days, no subscription).
Working a job, prereqs, and TEAS prep at once? Focus Mode strips the clutter so each short session actually counts.

A pass-probability score across all 4 sections - so you don't walk into a gated exam guessing.
The heaviest TEAS section gets the most adaptive drilling, with step-by-step explanations from Sage.
Every session targets your weakest sub-areas first, so your study time moves the needle.
Full-length, timed TEAS simulation that mirrors the real 4-section format and pacing.
TEAS Science engine
Science is the hardest TEAS section for most students, and Anatomy & Physiology is the biggest chunk of it. This preview turns that into a body-system workflow with a visible hotspot target, not a random question dump.
Hotspot preview
A&P hotspot focus
Which structure pumps oxygenated blood to the body?
Why it matters on TEAS
Cardiovascular items show up as diagram prompts and function prompts. Students need both the location and the job.
Common miss
Right/left chambers and arteries vs. veins get mixed up fast.
How this becomes a real product
Flow, chambers, valves, blood pressure.
Gas exchange, airflow, oxygenation.
Hormones, feedback loops, metabolism.
Pathogens, response, defense, inflammation.
A method-first guide to all four Science sub-domains — how to study Anatomy & Physiology system by system, plus Biology, Chemistry, and Scientific Reasoning — paired with 350+ targeted TEAS Science questions.

Use PrepLion to practice daily, find your weak areas, and build confidence - especially in Anatomy & Physiology, the heaviest Science sub-area. We are not the test maker: ATI publishes the official TEAS. Before test day, confirm your readiness with an official ATI practice assessmentand use your PrepLion readiness score to know where to focus until then.
