High-Level ACT English Guidance

A big mistake many students make is assuming that because they take tests in school all the time, they know exactly what to expect from the ACT. This test has its own special quirks, however, and learning how to navigate the ACT's unique structure and style is a key part of preparing for it and the English section specifically.


What’s Actually Tested on the ACT English Section?

The first step to tackling the ACT English section is to know what’s on it. This guide will help you understand how the ACT English is structured and what concepts it tests so that you can begin planning your prep.


5 Critical Concepts You Must Understand to Ace ACT English

The ACT English section has certain quirks that set it apart from a grammar test you might see in English class. In this article, you’ll read about the key big-picture concepts you need to understand in order to excel on this section of the test.


The Best Way to Approach ACT English Passages

It’s easy to ignore the passage format of ACT English, but doing so puts you at a real disadvantage. This post will help you understand why it’s important to have strategy for how to attack the ACT English passages and determine the best way for you to approach them.


How Often Is NO CHANGE the Right Answer on ACT English?

One of the most common mistakes students make on ACT English is assuming that there must be an error in every question. NO CHANGE is actually the answer more than 25% of the time it’s an option.


The Complete Guide to ACT Grammar Rules

The 14 ACT Grammar Rules You Must Know

The first article outlines all the concepts covered by ACT English, from punctuation to grammar, and the second one goes over the most important grammar rules that appear on the ACT. Use both articles to quickly review the rules and determine what you need to study further.




ACT English Skills

A key part of preparing for ACT English is learning rules covered by the test. I've listed our guides to all the major concepts below, split into Grammar and Usage and Rhetorical Skills, and organized roughly in order of importance (from the most commonly tested rules to the least commonly tested ones).


Grammar and Usage

Parts of Speech

The ACT English section doesn’t directly test parts of speech, but this guide outlines all the basics you need to know in order to understand the more complex topics.


Run-on Sentences and Fragments

Questions about sentence structure and correctly connecting independent clauses are the most common type on ACT English. Make sure you understand how to spot and fix run-ons and fragments.



On ACT English, commas are the single greatest source of confusion for most students. It's the most often tested punctuation mark on ACT English and appears very frequently. It’s vital to understand when you really need them so you can avoid overusing this tricky punctuation mark.


Other Punctuation

The other forms of punctuation you'll see tested on ACT English are semicolons, colons, dashes, and apostrophes. This guide covers them all!


Subject-Verb Agreement

Verb errors are another major topic for ACT English questions. Make sure you understand how to spot even the most well hidden agreement errors. For example, while the sentence, "Each of the siblings have their own rooms" might sound OK, the singular subject "each" actually requires the singular verb "has."


Verb Tenses and Forms

Issues with verb forms are a lot more common than you might think. For ACT English, you'll need to be especially familiar with problems such as inconsistent tense usage, confusion of would and will, and gerund errors.


Pronoun Agreement

The final major category of grammar issues is pronoun errors. Pronoun agreement, especially plural versus singular pronouns (e.g., it/he/she vs they), trips up a lot of students on the ACT.


Pronoun Case

You’ll see questions about pronoun case (e.g., me vs I) less often, but it’s still important to know what it is and how it’s tested. (Hint: the hard pronoun case questions usually involve compound objects.)



Idiom errors, which deal with the correct usage of prepositions and conjunctions (e.g., "talk to" vs "talk at"), are one of the most confusing topics on ACT English because they don’t follow any general rules. Make sure you know when to trust your instincts about which answer sounds right.


Faulty Modifiers

Both misplaced and dangling modifiers appear on the ACT English section. These errors, which involve descriptors that are separated from the nouns they're describing, usually aren’t obvious, so it’s important that you know how to spot them.


Parallel Structure

Items in lists and comparisons need to be in the same form—that’s the basic rule of parallelism. This guide will help you understand exactly where parallelism errors appear on ACT English and how to fix them.


Relative Pronouns

Relative pronouns are words, such as "who," "when," and "which," that introduce additional information. Common errors with relative pronouns are creating a fragment and using the wrong pronoun for what it’s describing.


Adjectives vs Adverbs

Adjective and adverb issues are relatively rare, but when they do appear on ACT English, they usually involve an adjective being used in place of an adverb (e.g., "He ran quick" instead of "He ran quickly"). You might also see questions about superlatives (most) versus comparatives (more).




Rhetorical Skills


Transitions are the most common type of rhetorical skills question on the ACT. These questions can be confusing, but learning a few simple tricks will make them much easier.


Wordiness and Redundancy

Another common rhetorical skills topic, redundancy is confusing because it’s not necessarily something that would be considered wrong when you’re talking or writing normally. Make sure you know what counts as redundancy on ACT English.



Add/Delete questions, which ask whether a sentence or phrase should be included or removed from the passage, are some of the most common and challenging rhetorical skills questions on ACT English. You need to know how to approach them systematically to succeed on the ACT.


Author Technique/Intent

The key to author intent questions, which ask about how best to achieve a certain effect, is reading them closely and understanding what they’re asking. This guide breaks down techniques for doing so effectively.


Macro Logic and Organization

Macro-logic is just a fancy term for questions that ask you where a sentence or paragraph should go. These questions tend to seem more complicated than they really are—make sure to use the process of elimination to narrow down answers.


Author Main Idea

Main goal questions, which ask about what the author's overall purpose is, are kind of weird because they seem to belong more on the reading section than the English one. Nonetheless, there’s usually one or two on each test, so it’s important to know how to answer them.



Like redundancy, relevance is tricky because it’s likely to be a concept you haven’t encountered in this form before. Relevance questions ask you to determine whether a piece of information is necessary in context.


Word Choice/Diction

Like idiom questions, word choice questions are tricky because they’re hard to predict and require you to have a deep knowledge of common English usage. Unlike idiom questions, however, they aren’t that common.



Questions that deal with formality are relatively rare—you might or might not see one on test day—so this topic should be one of the lowest priorities for your ACT English prep.

You can only improve so much by reading about the test—you have to try out the strategies and tips for yourself.

When doing so, make sure you also know the best way to review missed questions, since you can't improve unless you learn from your mistakes. In addition, I recommend looking over questions you guessed on and got right so you can ensure you know how to get the correct answer.

Overall, remember to balance your ACT prep by coming up with a foolproof study plan. And know that, with a little hard work, you can get a great score on ACT English!
