If you’re going to do well on the SAT, you’ll probably need to invest in some additional study materials beyond what you’re given in school. (And some schools may not provide SAT study resources at all!) 

SAT test prep costs can include buying study materials and practice tests, one-on-one tutoring, and taking SAT study courses. It’s a good idea to start asking “how much does SAT prep cost” now so that you can budget for the SAT test prep service that’s right for you.

But how much do SAT prep courses cost, exactly? In this article, we’re going to break down SAT prep cost and SAT coaching fees for self guided study, online programs, and one-on-one tutoring. That way you and your family can make sure your testing strategy fits within your budget. 

So let’s get started. 

Many students taking the SAT are most daunted by the Math section. There are a lot of questions covering a lot of topics that you need to answer in a short amount of time. Fortunately, you can enter the exam room feeling prepared and confident for SAT Math. This guide contains the 16 best SAT Math tips and tricks you should be using. They cover all the bases from the time you begin studying to the moment time is called on the exam and you put your pencil down.

What time is it? It's essay time! In this article, I'm going to get into the details of the newly transformed ACT Writing by discussing the ACT essay rubric and how the essay is graded based on that. You'll learn what each item on the rubric means for your essay writing and what you need to do to meet those requirements.

Sometimes writing—especially writing for standardized tests—can feel like something you "get" or "don't get." That's primarily because it's very difficult to explain and teach writing in a mechanical way, especially when you're up against time limits.

In this article, we've broken how to write the ACT essay into eight steps that work for every essay, every time. Then, we show you exactly how to do it with an actual ACT essay example.

Triangle questions account for less than 10% of all SAT math questions. That being said, you still want to get those questions right, so you should be prepared to know every kind of triangle: right triangles, isosceles triangles, isosceles right triangles—the SAT could test you on any one of them. Since triangle problems only account for a small percent of the SAT math questions, you shouldn’t spend all of your study time on triangles.

Mission control. Command center. Control tower. No, I'm not talking about space or your laptop hard drive, or even airport flight control. I'm talking about the human brain—the most complex and essential organ our bodies have. What is the brain structure? What part of the brain controls emotions?

Whether you're studying it in class, preparing for an AP exam, or just curious about brain structure, in this article, you'll learn about the main parts of brain anatomy and their functions and as well as get a general overview of the brain's supporting cast.

If you've just taken the IELTS, you're probably anxious to see your scores. Did you do as well as you needed to do on this tricky English proficiency exam or not? When will you get your official IELTS score report, and when will you be able to see your IELTS results online?

We answer these questions and give you an explanation of what will be on your IELTS score report. We also offer some tips for what to do with your IELTS test results once you get them.

Functions. Just hearing the word is enough to send some students running for the hills. But never fear! Though function problems are considered some of the more challenging questions on the ACT, this is only due to the fact that most of you will be far more used to dealing with other math topics (like fractions, exponents, or circles) than you are functions.

On the ACT, question difficulty is categorized by how familiar you are likely to be with any given question, and the only way to combat this challenge is to practice and get used to dealing with questions that are a little less familiar to you. You will generally see 3-4 function questions on any given ACT, so for those of you who are not yet comfortable with functions (or just want a tune up), this guide is for you.

This will be your complete guide to ACT 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 ACT.

Every test requires some kind of preparation—even the SAT. Most students choose to prep entirely on their own for the SAT, which can have a lot of advantages (but also some potential drawbacks). So how does SAT self-study actually work? How can you ensure you get the most out of your SAT self study plan? Read on for our answers!

While you may have been told you need zero science knowledge to answer any ACT Science questions, this is NOT true. There are typically around four questions per test that you cannot answer without previous background knowledge. That's the difference between a 31 and a 36 on the Science section!

In this article, I will give an overview of the 18 topics that will NOT be explained in the ACT Science passages that the ACT expects you to know. The ACT assumes you know these topics from school and science class. To gather this info, I dissected dozens of previous ACT Science test sections to find the concepts you have to know. As far as we can tell, we're the only ones who have taken the time to research this.

If you've gotten bad grades in science classes in school, this article will give you a refresher on the only concepts you need to know.
