SAT / ACT Prep Online Guides and Tips

If you’ve been hard at work studying for the ACT, you’ve mastered the basics of the test. But are you ready to tackle the hardest grammar, punctuation, syntax, and writing logic questions that ACT English will throw at you?

To help you prepare, we'll explain the hardest ACT English question types you'll face on the ACT. For each type, we'll give you at least one practice question you can use to test your knowledge (and explanations so you know how to find the right answer). 

Ready? Let's get started.

Many students are aware that you need a good vocabulary to do well on the ACT, but they're often not sure just how their vocabulary will be tested. Gone are the days where you needed to learn the definitions of dozens of obscure words, but a good vocabulary is still key to excelling on the ACT. To help you out, we've compiled a list of 163 key ACT vocabulary words to know. We also explain how vocab is tested on the ACT, the types of questions you'll see, and the best way to study ACT vocab words.

Even though the English language is complex, ACT English tests a specific set of grammar rules. Furthermore, it tests these rules the same way, over and over again.

In this complete guide, we've compiled the comprehensive list of ACT English grammar rules you need to know to ace the ACT English section. If you master all these rules and practice them with realistic ACT questions, you'll have a huge advantage on the English section.

Are you struggling with ACT English scores between 14-24? You're not alone—hundreds of thousands of other students are scoring in this range. But many don't know the best ways to break out of this score range and get 26+ on the ACT.

Here we'll discuss how to improve ACT English score effectively, and why it's so important to do so. Put these principles to work and I'm confident you'll be able to improve your score.

Pronoun agreement errors are an especially confusing type of ACT English question because people often misuse pronouns, especially when you speak. In fact, I just made a pronoun mistake: can you spot it?

Take a closer look at the second half of my first sentence: "people often misuse pronouns, especially when you speak." Who is "you" referring to here: "people." However, the correct pronoun for the third person plural is "they." The correct version of the sentence is "people often misuse pronouns, especially when they speak."

On the ACT English section, you'll be expected to spot these kind of errors in a variety of different contexts. I'll go over both the basic rules for pronouns and the common mistakes you'll see on the test, so that you can approach the test with confidence.

Nobody likes commas: they're weird and confusing and possibly pointless. My brother decided to boycott them entirely in his senior year of high school, leaving his lists running together and his appositives undefined. Even veteran copy editors sometimes struggle with where exactly to place these reviled punctuation marks. 

Even so, if you want to succeed on the ACT English, you'll have to learn how to expertly employ commas. The good news is that there is a fairly limited set of comma rules you'll need to know for the ACT.

One of the trickier concepts that you will be tested on ACT English is your ability to choose the right word from among many that are not quite right, and to spot when words are being used incorrectly.

Are you confident in your ability to find the differences in a group of similar words? Can you distinguish what’s needed from the context of a question?

You may think that of all the grammatical concepts you will encounter on the ACT English, recognizing a correct sentence will be one of the easiest ones. But did you know that this is actually one of the most commonly-tested subjects because it can be very tricky?

Do you know what you need to have in order to have a complete sentence? Can you reliably tell the difference between a subordinate clause and an independent clause? Do you know how to use semicolons and conjunctive adverbs?

Read this guide to see how the ACT manages to trick so many students with this seemingly easy concept.
