The ACT Science Test: Biology Review 2

The ACT Science Test will test your understanding of the methods and procedures of scientific experimentation, your ability to analyze scientific information, and your ability to interpret and make inferences about data. The Science Test will not directly test your recall of specific facts or vocabulary. However, familiarity with basic terms and concepts in various scientific disciplines will help ensure that you understand the information presented in passages, charts, and graphs. To help you prepare, we've compiled fundamental terms from each of the major scientific disciplines covered on the exam.
