SAT / ACT Prep Online Guides and Tips

Many SAT math questions involve the use of integers, especially in the early and middle ranges of each math section. This means that integers are a foundational element to SAT math and you should have a solid understanding of what integers are and how they work if you want to do well on the SAT math section.

This guide will cover the basics of integers—what they are, how they relate to one another, and how you’ll see them on the test. For the more advanced integer concepts (including prime numbers, absolute values, exponents, and roots), check out our advanced guide to SAT integers.

Geometry is the branch of mathematics that deals with points, lines, shapes, and angles. ACT geometry questions will test your knowledge of the shapes, sizes, and volumes of different figures, as well as their positions in space. 33% of ACT math problems (about 18 questions total) will involve geometry, depending on the particular test.

Because geometry as a whole covers so many different mathematical concepts, there are several different subsections of geometry (including planar, solid, and coordinate). We will cover each branch of geometry in separate guides, complete with a step-by-step approach to questions and sample problems. 

This article will be your comprehensive guide to solid geometry on the ACT. We’ll take you through the meaning of solid geometry, the formulas and understandings you’ll need to know, and how to tackle some of the most difficult solid geometry questions on the ACT math section.

Because the ACT is designed to be taken by every high school student in the country, it can only test math concepts that every student has experience with. The way the creators of the test make it hard is by giving you questions on a wide range of subjects and sub-topics, presenting them in strange ways, and by putting you on a strict time crunch. 

Maybe you’ve taken the ACT before--whether practice or real--and found yourself only half way or three quarters of the way through the math section before your time was up. Maybe you just think it would be downright impossible to finish so many questions on time. Rest assured--you are not alone. And it is not impossible.

In this guide, I'll walk you through the timing of the test and teach you how to beat the clock and maximize your time on the ACT.
