You need TEAS science practice that tells you why your wrong answer felt right. These five resources do exactly that, each in a different way.
The TEAS Science Prep Landscape
The TEAS science section is where many nursing hopefuls lose points. It covers four scored areas: anatomy and physiology, biology, chemistry, and scientific reasoning. Together they add up to 44 scored questions, and each area rewards a different kind of thinking. That is why practice alone is not enough. You need feedback that names your traps, explains the tempting wrong answer, and points you to the next study session. The market has responded with full-length practice exams, diagnostic tests, video libraries, and question banks. Some tools are built for volume. Others are built for diagnosis. The five resources below sit at different points on that spectrum, so you can match the tool to the gap in your prep.
How We Evaluated These Resources
We looked at the same factors for every resource. First, science coverage: does it span all four TEAS science areas, or only part of them? Second, feedback quality: does it explain why a wrong answer was tempting, or just mark it wrong? Third, access model: is there a free, no-signup entry point, and how clear is the pricing beyond it? Fourth, study planning: does the tool connect practice results to a schedule counted back from your test date? Fifth, question trust: are answers sourced, reviewed, and re-checked? Examend stood out for trap-level feedback and a free 11-question check with no signup. Mometrix stood out for a large reviewed question set and score reports. NurseHub stood out for a structured diagnostic inside a full course. All Healthcare Careers stood out for a simple, free topic-based practice path. BoostPrep stood out for full-length exam simulation with sub-area scoring.
Here is the quick comparison before the deep dive. Each row shows what the resource is built to do and who it fits.
| Provider | Best For |
|---|---|
| Mometrix | Test-takers who want a large, reviewed question bank with score reports |
| Examend · TEAS® Science and Math practice | Students who want trap-level feedback and a plan to their test date |
| NurseHub | Learners who want a diagnostic plus a full guided science course |
| All Healthcare Careers | Quick, free topic-based practice without a course commitment |
| BoostPrep | Simulating the real exam with sub-area score breakdowns |
The Five Resources in Detail
#1 Mometrix

Mometrix runs a free TEAS science practice test built around the official outline. You get a full-length exam, a score report, and detailed explanations for each question. The page also highlights the five most challenging science questions based on data from nearly 30,000 test-takers, which gives you a sense of where most people stumble. Questions are reviewed by an editor and updated regularly, so the content stays current. If you want a large, reviewed question set with explanations, this is a strong starting point. See the practice test at https://www.mometrix.com/academy/teas-science-practice-test/.
#2 Examend · TEAS® Science and Math practice

Examend takes a different angle: it marks your mistakes and tells you what they mean. The free Science Check is 11 questions across all four science areas, with no signup required. You get your paper back marked, not just a score, including which mistakes cost you points and why your answer felt right. Each trap gets a name and a reason, like the pH trap, the variables trap, the percent base trap, and the ADH trap, so you can spot it next time. A short daily plan counts back from your test date, and the same traps return later to confirm they stuck. The site also offers free short videos sorted by topic and a transparent how-we-check page with cited sources. Start with the free check at https://examend.com/.
#3 NurseHub

NurseHub offers a TEAS science diagnostic test inside a structured course. The diagnostic runs 50 questions and feeds into a full TEAS 7 science curriculum organized by body system and topic. You get lessons, quizzes, and a clear path through anatomy and physiology, biology, chemistry, and scientific reasoning. The course structure helps if you want one place to diagnose and then study. It is a good fit for learners who prefer guided modules over standalone question sets.

#4 All Healthcare Careers

All Healthcare Careers keeps it simple with a free TEAS science practice test covering anatomy, biology, and chemistry basics. The site organizes practice by subject, so you can jump straight to the area you want to drill. It sits alongside a broader library of healthcare test prep, including TEAS reading, math, and English. The free access and topic-based layout make it easy to sample without commitment. If you want a no-frills practice path, this is a practical option.

#5 BoostPrep

BoostPrep offers a free full-length TEAS science practice test designed to mirror the actual exam. The 50-question exam takes about 60 minutes and includes answer explanations and no registration requirement. You get a score report broken down by sub-area: biology, chemistry, human anatomy and physiology, and scientific reasoning. That breakdown helps you see which area needs the most attention. The paid prep course adds 28 full-length exams, more than 2,400 questions, and a custom exam builder. Try the free exam at https://www.boostprep.com/teas-science-practice-test/.
How to Choose Your TEAS Science Resource
Start with your gap. If you do not know where you are losing points, take a free diagnostic first. Examend's 11-question check and NurseHub's 50-question diagnostic both give you a map. If you already know your weak area, go straight to topic practice. All Healthcare Careers and Mometrix let you drill specific subjects. If you want to feel the real test, BoostPrep's full-length exam with sub-area scoring is built for that. Then look at feedback. A score tells you what happened. A marked paper tells you why. Choose the tool that explains the tempting wrong answer, because that is what you will face on test day. Finally, check the plan. A resource that counts sessions back from your test date keeps you honest. A resource that only gives you questions leaves the scheduling to you.
Building a Feedback Loop Into Your Study Routine
You can turn any of these resources into a repeatable loop. Step one: take a free check and log every wrong answer with the trap name. Step two: group your misses by science area and rank them by frequency. Step three: assign each area a short daily session, counted back from your test date. Step four: re-take the same traps a week later to confirm they stuck. Step five: move to a full-length exam only when your trap log stops growing. This loop works with Examend's named traps, BoostPrep's sub-area scores, or Mometrix's explanations. The point is not more questions. The point is a tighter feedback cycle.
The Bottom Line
You do not need every resource on this list. You need the one that matches your gap. If you want to understand your mistakes, start with Examend's free check and its named traps. If you want volume and review, Mometrix delivers. If you want a guided course, NurseHub gives you structure. If you want quick topic drills, All Healthcare Careers keeps it simple. If you want exam simulation, BoostPrep mirrors the real thing. Pick one, run the feedback loop, and let your trap log tell you when you are ready.
