The College Board is going to allow students who were affected by the mistake on the June 6, 2015 administration of the SAT to re-take the test for free in October. Read on for more information and to see what your options are.

As a high school student, you’re probably wondering whether you should take the SAT or the ACT. Which one will give you a better score? Is one easier than the other?

In this article I’ll go through a list of different strengths and weaknesses you might have as a test-taker and student and let you know which test you should take based on those qualities.

The SAT and the ACT are both hard pills to swallow, but one might be easier for you than the other. If you're still trying to decide which test to take, these charts will give you direct comparisons between them in terms of format, timing, and content. Then you can figure out which one sounds like the right fit for you!

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.

ACT English tests you on a number of specific grammar rules. Being able to understand and apply these rules will help you maximize your ACT English score. Besides knowing specific grammar rules, there are some general strategies to keep in mind that will help you correctly answer more questions. 

One of these tips is that the ACT prefers shorter sentences. Wordiness and redundancy are common errors on the ACT English section. The goal for each sentence is to express the same information in the shortest grammatically correct way.

Every SAT test has 6 special questions in the writing section that test not just your grammar skills, but how well you are able to use them in context. Can you tell which correct version of a sentence best suits the paragraph that it’s in? Are you ready to tackle one of the most unique parts of the SAT?

Oftentimes, if I make an outlandish comparison, someone will turn to me and say, "You can't compare apples and oranges, Alex."

Grammatically speaking, however, you absolutely can compare apples and oranges—they're both fruits! However, it's true that some comparisons are nonsensical, like a comparison between apples and eating apples.

This kind of construction is called an illogical comparison, and it's one of the most unusual concepts on SAT Writing. Though essentially simple to spot, illogical comparisons are unfamiliar for most students because they rarely come up elsewhere. 

A general rule to follow when answering SAT Writing questions is that the given sentence should be written in the most concise grammatically correct way. Often, especially in sentence improvement questions, the error in a sentence is only that the sentence is too wordy. Similarly, sometimes specific words in a sentence can be eliminated because they are superfluous. Wordiness and redundancy are common errors on the SAT Writing section, and I will be explaining how to identify and correct these errors.

“Parts of speech” is a fancy way of saying that every word in the English language can be put into one of eight categories, depending on how it is used. Of these eight parts of speech, only 7 are tested on the Writing SAT and on ACT English.

Understanding the different parts of speech is absolutely essential to having a firm grasp of English grammar, and in succeeding on the SAT and ACT. Unfortunately, nowadays many schools no longer focus on teaching this type of grammar.

Are you a bit unsure about what, exactly, a preposition is, or can’t tell the difference between an adjective and adverb? Feeling a bit rusty after learning this years ago? This article will provide the foundational information you need before moving on to more complex grammatical concepts. I'll also go over a few important SAT/ACT grammar rules.

You may recall the good ol’ days of elementary school when you learned about adjectives and adverbs. If you had realized that you would have to know about these parts of speech for the SAT, perhaps you would have paid better attention instead of daydreaming about Nickelodeon and The Disney Channel.

Don’t worry. If you’ve forgotten or never learned about these parts of speech, I’ll teach you everything you need to know about them for the SAT Writing section.

The SAT tends to be seen as an immutable barrier that all students must overcome before getting into college. But standardized testing is a business, and the College Board has its own motivations behind maintaining the status of the SAT as the definitive test for college readiness.

In this article I'll take a look at SAT history, its successes and failures, its motivations, and how it might evolve in the future. 

Like most ACT Science questions, Interpreting Experiments don’t require you to understand the hard science behind the experiments. Instead, these Interpreting Experiments questions will give one interpretation of part of the passage and ask you whether that interpretation is true or not, using the data from the experiment. These questions have a predictable pattern to the question and answers, which you can use to your advantage.

In this article, I'll cover the general format of Interpreting Experiments Questions, solve several ACT Science practice questions, and provide ACT Science tips to answer these questions.

Many students struggle with ACT Science. Students, who came to me for tutoring after taking their first official ACT test, typically performed worst on this section. It is very fast and unlike any other science test. This section more than any other is about pacing and strategy. I was able to boost my ACT Science score 5 points with a few tips. So, what simple tips and tricks can you use to boost your ACT Science score right now?
