How to Use This ACT Study Guide
This ACT study guide collects our most important ACT articles on every topic, from general info to key test-taking tips and specific section content. Without a doubt, all of these topics are critical for making the most of your prep and staying confident on test day.
We’ve arranged the following guides in roughly the order we recommend reading them, starting with a basic overview of the ACT and moving on to high-level strategies.

Intro to the ACT
All beginners to the ACT should start with the basics. In this section, you'll learn how the test is structured, what kinds of questions and content it tests, and what its scoring scale means for you.
You’ll likely need to take the ACT or SAT to get into college, but how important is your ACT score to schools? And how can you use this knowledge to raise your chances of getting into the college of your dreams? This extensive guide explains why colleges look at ACT scores and how they use ACT scores to compare students across the country.
This article lays out all of the fundamentals of the ACT: how it started, what it tests, and why you need to take it. It also offers a few tips on how to get started on making an ACT study plan.
You'll need to familiarize yourself with the four ACT sections. Our individual section guides explain what you can expect on each section in regard to content and question types.

Before taking the ACT, it's important to know what the average ACT score is and what percentiles are. Our guides give you the overall ACT average, explain how this average can vary by college and state, and go over how to use percentiles to compare your performance with other test takers'.
Everyone wants to get a good ACT score on test day. But what’s more important than hitting a certain percentile is getting a score that’s right for you. This guide explains how to figure out what a good ACT score for you is and how to set a target score based on where you're applying.
