Why Practice Tests Are the #1 Predictor of Exam Success

If you could only use one study technique, research overwhelmingly recommends practice testing. A landmark 2013 meta-analysis published in Psychological Science in the Public Interest rated practice testing as the most effective learning strategy — above highlighting, summarizing, and re-reading.

The Testing Effect

The act of retrieving information from memory during a test strengthens the memory itself. This phenomenon, known as the “testing effect,” means that every practice question you answer is actively strengthening your knowledge — even if you get it wrong.

Identifying Knowledge Gaps

Practice tests reveal what you do not know. Without them, students often fall into the “illusion of competence” — feeling confident because the material seems familiar, but struggling when asked to apply it independently.

Reducing Test Anxiety

Familiarity breeds confidence. Students who regularly take practice tests experience less anxiety on exam day because the format, timing, and question styles feel natural rather than intimidating.

Improving Time Management

Practice tests teach you to allocate time effectively. You learn which question types to tackle first, when to move on from a difficult question, and how to pace yourself throughout the exam.

How Many Practice Questions Do You Need?

Research suggests completing 3-5 times the number of questions on the actual exam provides optimal preparation. For a 100-question exam, aim to practice 300-500 questions across your study period.
