How to pass the TEAS

The TEAS rewards steady practice on a fixed list of topics. Find your weakest section with a practice test, study that first, and finish with timed sections.

1. Start with a baseline

Take a free TEAS practice test before you study. Your section scores show where the points are, and that is where your first week goes.

2. Science is the biggest section

  • Learn the body systems one at a time: main organs, what each does and how it connects to the next (for example how blood moves through the heart and lungs).
  • Add cells and genetics (organelles, DNA, mitosis and meiosis, Punnett squares), then chemistry basics (atoms, bonding, pH, reactions).
  • Practice scientific reasoning: name the variable that was changed, the one measured and the one kept constant in a short experiment.
  • Make flashcards of the terms you miss, and test yourself out loud.

3. Math: set up before you calculate

  • Memorize the conversions: 1 g = 1,000 mg, 1 L = 1,000 mL, 1 lb = 16 oz, 3 tsp = 1 tbsp, 2 cups = 1 pint.
  • Practice percent, percent change, ratio and proportion problems until you can set each up in 15 seconds.
  • Estimate the answer first so a slipped decimal point stands out.
  • Know your fraction to decimal pairs and how to read a small table or chart.

4. Reading and English

  • Reading: read the question first, then the passage, then find the exact sentence that answers it. Wrong options are often true in general but not stated in the passage.
  • Learn the question types: main idea, detail, inference, author's purpose and word meaning in context.
  • English: review subject-verb agreement, pronoun reference, commas and semicolons, apostrophes and the confusable words (affect and effect, its and it's).
  • When two options both look right, read each one aloud and pick the one with no error.

5. Pace each section

Pacing is roughly 73 seconds a question in Reading, 90 in Math, 72 in Science and 60 in English. Mark and return to a hard question within the section, because you cannot return to a section once it ends. There is no penalty for a wrong answer, so never leave a question blank.

6. A two-week plan

DaysWhat to do
1Full timed practice test. Note your score by section.
2 to 4Study your weakest section for an hour a day, with practice questions after each topic.
5 to 7Study the second weakest section. Review every miss and write the rule in one line.
8Second full timed test.
9 to 12Fix what the second test exposed. Alternate science review with timed math practice.
13Third timed test.
14Rest, light review of flashcards, check your ID and test-center rules.

Frequently asked questions

How long should I study for the TEAS?

Two to six weeks is typical. Two weeks of focused study can work if you start from a decent baseline and fix your weakest section first.

What is the hardest section of the TEAS?

Most people say Science, because it is the longest and covers the most facts. Math is the other common weak spot because of conversions and percent problems.

Should I guess on the TEAS?

Yes. A wrong answer does not cost more than a blank, so answer every question.

Can I go back to earlier questions on the TEAS?

Within a section, yes. Once you finish a section or time runs out, you cannot return to it.

Is the TEAS practice test on this site free?

Yes, the full test and your estimated score are free with no sign-up. The prep pack adds explained answers, two more tests and a 7-day plan.
