What’s In The ACT Science Test?

Here’s a brief description:

There are 40 questions that comprise the ACT Science Test that you have to finish responding to in 35 minutes. Your skills in interpreting, analyzing, evaluating, reasoning and problem-solving pertaining to the natural sciences will be measured in this test.

Various sets of scientific information are presented in the test with each of them followed by a series of multiple-choice test questions. Three different formats signify these scientific information, and namely they are 1) data representation such as tables, graphs and other schematic forms, 2) research summaries such as descriptions of varied related experiments, and 3) conflicting viewpoints that express a number of related views or hypotheses that are contradictory to one another. The questions aim to evaluate how well you are cognizant and comprehend the basic features and concepts that pertain to the presented information. Can you critically examine how the provided information and the derived conclusion or developed hypotheses relate to each other? You should be able to generalize and obtain new information from a given one. Other than drawing conclusions, you will likewise be asked to make predictions. In some of the test items, you should be able to deliver knowledge about discipline-specific content. The ACT Science test assesses science content in congruence with science skills and practices.
