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 […]

ACT matrices problems may look intimidating, but learning a few simple steps to approach them (and doing some quick practice!) will help you master them.

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 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 […]

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, […]

Probability is actually pretty rare on the SAT. So don’t freak out about this topic. In fact, I’d only recommend this post for those looking for a near perfect—those who want to make sure they have all their bases covered. What you’ll have to know is the following: Probability (Likelihood of something happening) = #of […]
