The ACT Science Test will always be the fourth test you’ll take. It will have 7 passages and you’ll have 35 minutes to complete them.

In a previous post, we took a look at two different types of “averages” you might see on the ACT Math Test, one of which was a fairly rare challenging concept known as “average speed. Often found in complex word problems, this type of question is one many students are less familiar with so don’t […]

Some ACT Science questions ask about the hypotheses each experiment is based on – some will ask you to weaken and some will ask you to strengthen these hypotheses. For the weaken questions, you must fully understand the set-up behind the experiments in order to know whether the results will weaken a conclusion. Try a […]

The good news is that while you do NOT have to be an excellent science student to score highly on the ACT Science test, some knowledge of the concepts tested and a familiarity with the presentation of certain concepts will almost certainly lead to better scores! 🙂 Passages dealing with Biology may involve body systems, […]

In Data Representation, Research Summaries, and Conflicting Viewpoints passages, you will need to be able to understand how scientific evidence is presented and answer questions based on this evidence. These are a lot like “Detail” questions on the ACT Reading Test. To answer “Interpreting Evidence” questions correctly, ask yourself these 3 questions: 1. What type of […]

Conflicting Viewpoints: Understanding Point of View As you read each ACT Science passage, look closely for keywords that help you identify each scientist’s opinions. What does the author like? What does he dislike? What adjectives and adverbs does he use to describe the various scientific topics? He may feel positively about one thing, and negatively […]

ACT Math Basics Learning the basics of number properties is crucial for success on the ACT Math Test. Here, you’ll learn some basic terminology to help you on the test. A factor, or divisor, of a number is a positive integer that evenly divides into that number. For example, 4 is a factor of 12 […]

A fraction consists of a numerator, a fraction bar, and a denominator. To add or subtract fractions, you just need to find a common denominator. For example ¼ + 1/3 = 3/12 + 4/12 = 7/12. All fractions are rational numbers. A rational number is a number that can be expressed as a ratio of […]
