Coordinate geometry is a big focus on the ACT math section, and you’ll need to know its many facets in order to tackle the variety of coordinate geometry questions you’ll see on the test. Luckily, coordinate geometry is not difficult to visualize or wrap your head around once you know the basics. And we are here to walk you through them.

There will usually be three questions on any given ACT that involve points alone, and another two to three questions that will involve lines and slopes and/or rotations, reflections, or translations. These topics are tested by about 10% of your ACT math questions, so it is a good idea to understand the ins and outs of coordinate geometry before you tackle the test.

This article will be your complete guide to points and the building blocks for coordinate geometry: I will explain how to find and manipulate points, distances, and midpoints, and give you strategies for solving these types of questions on the ACT.

Looking for some quick fixes to improve your ACT scores? Look no further. In this article, we give you several tips and tricks for the ACT so that you can get your best possible scores on every section.

SAT functions have the dubious honor of being one of the trickiest topics on the SAT math section. Luckily, this is not because function problems are inherently more difficult to solve than any other math problem, but because most students have simply not dealt with functions as much as they have other SAT math topics.

This means that the difference between missing points on this seemingly tricky topic and acing them is simply a matter of practice and familiarization. And considering that function problems generally show up on average of three to four times per test, you will be able to pick up several more SAT math points once you know the rules and workings of functions.

This will be your complete guide to SAT functions. We'll walk you through exactly what functions mean, how to use, manipulate, and identify them, and exactly what kind of function problems you'll see on the SAT.

Are you struggling with ACT Math 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 Math 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.

In this article, we’ll go over how to calculate target SAT Math, Reading, and Writing scores, as well as why you might want to do this.

Are you trying to get rid of your allergy symptoms but Claritin doesn’t work for you? Claritin is one of the most popular allergy medications on the market, but for some people it just doesn’t work. Why is this?
