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, […]

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 […]

Easy ACT Science Test questions ask you what the passage or data tables explicitly say. More challenging questions require you to draw your own conclusions based on what is implied in the passages. Mark up the passages as you read, paying close attention to the topic, experiment set-ups, given results, author’s point of view, and […]

Not all averages are created equal on the ACT Math Test. What can be somewhat confusing is that the word “average” on the ACT Math can refer to two separate concepts: the arithmetic mean, and the average speed. It’s important not to confuse the two on the Test Day, as they require different formulas to […]

Function questions are among the toughest problems you might see on the ACT Math Test. These questions sometimes ask about domain and range, or present you with a linear or quadratic function and ask you to plug in a number for a variable and solve. Functions can also use made-up symbol. For these tricky problems, […]

On the ACT Science Test, assumption questions will either ask you to apply a given set of information to a new situation or ask you to correctly identify the basis for a conclusion. What is an assumption? In an argument, an assumption is an underlying basis for a conclusion. It is something that needs […]
