About ACT® Science Test

The Science section on the ACT® evaluates your interpretation, analytical, and problem-solving skills. The questions check your knowledge of the natural sciences, including physics, chemistry, biology, and earth/space sciences (geology, astronomy, and meteorology). In this section, you are required to show your understanding of concepts related to the information given in passages, develop hypotheses, draw conclusions, or make predictions.

This all-in-one ACT Science guide explores the format, syllabus, question types, and scoring pattern of the test. We also discuss what science is on the ACT and share some study tips in order to help you prepare more effectively.

ACT Science Format and Syllabus

On the ACT Science test, there are seven passages followed by 40 questions to be answered in 35 minutes. In this section, the scientific information is presented in one of the following formats:

Though the passages and questions are based on science topics, you do not need to master the details of every scientific fact. Instead, you are asked to comprehend, analyze, and evaluate scientific information within the graphs, tables, charts, and diagrams given in the passages.

What types of questions are on the ACT Science test?

You will find three types of ACT Science questions on your test ‒ Interpretation of Data, Scientific Investigation, and Evaluation of Models, Inferences, and Experimental Results. All of the questions in the science section are multiple-choice.

  1. Interpretation of Data Questions

    About half of the questions on the ACT Science test are Interpretation of Data Questions. These questions focus on your ability to read a graph, evaluate trends in the data, and translate information from the given graphics. You should be able to summarize the information in a graph, table, or scatterplot. Expect to answer questions that ask you to use the information in the passage to select a graph that reflects specific relationships, correlations, or findings from the text.

  2. Scientific Investigation Questions

    These questions will assess your understanding of how an experiment is designed. You will use this understanding to answer questions about additional factors, tests, or trials. Some of these questions will ask you to pinpoint the different factors in the experiment. Other questions will require more steps to draw comparisons. You may have to make adjustments to the procedure and draw conclusions based on the changes.

  3. Evaluation of Models, Inferences, and Experimental Results Questions

    These questions assess your ability to apply the information in the passages to various conclusions. You may be presented with a conclusion to decide whether it is valid, given the results of the study, the data in the model, or the inferences made throughout the text. You may also have to use the results in a passage to draw conclusions and make predictions of your own.

Can I use a calculator on the ACT Science test?

No, using a calculator on the ACT Science test is not permitted. You can only use a calculator in the math section.

Is the ACT Science Section Hard?

The ACT Science section is quite different from your school science tests or AP exams. The unique format and content of the ACT science section often presents a challenge to students. Generally, students find it easy to solve questions that require data interpretation. However, questions that require drawing conclusions from multiple data sources are more complicated, as they are more difficult to get right. In addition, keeping up with the pace of the test can be overwhelming because you get less than a minute to spend per question. While you may be able to answer some questions without reading the passage by just interpreting the graphs and charts, other questions may consume more time since they require choosing the right information from the passage.

However, the ACT Science section is not as difficult as it seems. Remember that the test is checking your understanding of scientific reasoning rather than your knowledge of scientific facts. With the right amount of practice, you will be able to increase your familiarity with how to respond to each question type and get used to completing the test within the allotted time.

What level of science is on the ACT?

You are not required to have advanced knowledge about science subjects to be successful on the ACT science test. However, you will find questions related to concepts and theories learned in general introductory science courses.

How to Calculate ACT Science Score

The ACT Science score ranges from 1-36 and is calculated by converting the raw scores to scaled scores. Your raw score is the number of questions you answer correctly on the test. There is no penalty for wrong answers or the questions you leave blank. The raw score of a section depends on the number of questions present in it. Since there are 40 questions in the Science section, the raw score range for this section is 0-40. After your raw score is calculated, it is converted to a scaled score of 1-36.

What is the passing score for the ACT science test?

There is no passing score for the ACT Science test. However, many colleges might not admit students with below-average scores.

What is a good ACT science score?

A good ACT Science score can be determined by the average ACT score for a particular year. Getting an above-average score is considered good.

What is the average ACT science score?

Depending on the number of test-takers, the average ACT Science score may vary from year to year. In 2022, the average ACT Science score was 19.9.

What is a bad ACT science score?

If you score less than the average science score for a particular year, it might be regarded as a low score.

ACT Science Test Prep Tips

Let's review the best ways to achieve a high ACT Science score:

  1. Learn what is tested on the science section

    It is important to know the test structure, question types, and format of the passages so that nothing catches you by surprise on test day.

  2. Know your areas of improvement

    To prepare for your test effectively, identifying your growth opportunities allows you to focus your attention and study efforts. Learn more tips and strategies for improving your science score in our ACT Science study guide.

  3. Save time wherever possible

    Many questions have their answers in the given tables and graphs. If you skim passages, it will save you valuable time.

  4. Avoid careless mistakes

    Careless mistakes can be a big setback. You might know how to solve a question, but a lack of focus or too much nervous energy can make you commit an error. Both timed and untimed practice ahead of the exam helps train your mind to respond to questions with more calm and focus.
