Exponents, or powers, are numbers that tell us to how many times to multiply a number by itself. For example, 26 = 2 * 2 * 2 * 2 * 2 * 2. You might read this as “two to the sixth power,” and our answer would be 64. For the ACT Math, you’ll really […]
Before we discuss strategies and tips for interpreting graphs, charts and tables, we first need to know the use and purpose of each. Charts and graphs organize, categorize and compare data. They come in various shapes and sizes (e.g., pie, bar, line). They commonly use columns, symbols and/or pictures to show the information needed to solve […]
Averages, or arithmetic means, are likely to show up on the ACT Math section. Most of us know how to find the average, but the test will probably present average questions in a more complicated way. Rather than present you with all the numbers in a set and ask you to find the average of […]
The ACT Math Test is always the second test and comes right after the English Test. It is always 60 minutes long and consists of 60 questions. Concepts tested include arithmetic, algebra, coordinate geometry, plane geometry, and (unfortunately) trigonometry. The math concepts get harder as you progress, so timing is an important part of the […]
A system of equations is a set of two or more equations that have two or more variables. “Solving” the system of equations means finding values for each of the variables that make each equation true. You probably remember from school that there are a few different ways to solve a system of equations. This […]
In this series, we will cover many types of geometric scenarios encountered on the SAT Math test. A basic knowledge of simple formulas (area, perimeter, etc.) is essential, but there are numerous shortcuts to geometry questions that will save you time. Today, we’ll explore circles inscribed in squares. Some Things to Remember The center […]
The ACT English portion is unlike the SAT Writing in that it requires a more holistic understanding of English grammar. The SAT’s single-question format is conducive to formulaic errors that, while tricky, can be narrowed down to a handful of inconspicuous grammar mistakes. The ACT English, on the other hand, features a wider variety of […]
When it comes down to identifying grammar errors in a sentence, you really cannot afford to overlook the dynamic duo of the grammar world: independent and dependent clauses. A clause is an expression (group of words) that includes both a subject and a verb. The difference between the independent and the dependent clause is simple: […]
If you’re looking to boost your ACT English score, there are lots of small things you can do to make a difference quickly. Try out the following suggestions:
Redundant phrases are those that unnecessarily repeat information. Redundancies are so common in everyday speech that it’s easy to overlook them. For example, examine the seemingly faultless sentence “I have to use the ATM machine, but I forgot my PIN number.” There are two errors of redundancy in this sentence: ATM stands for Automated Teller […]
