Magoosh’s New eBook: Lightening the SAT Math Load

Magoosh_SAT MathFor some high school students, SAT math is the bane of their existence. You need to learn all these foreign strings of numbers and letters, and then magically recall them once you’re sitting in a hot room for hours with your entire future weighing down on your tired shoulders. Yeah – SAT math…not the funnest thing in the world.

Our friends at Magoosh SAT have released a new ebook, Magoosh’s SAT Formula eBook, loaded with all you need to know to lighten the load and ace the math section on the SATs. The book is free with interactive elements, and comes complete with all the math formulas, study strategies, time-saving tips, and practice problems you’ll need for the SAT.

Here’s an excerpt from the intro of the book:

While formulas can be really helpful on the SAT, there are very, very few that you absolutely need to have memorized to score well. That might come as a surprise, but it’s true, and it leads us to an important thought: understanding how and why a formula works is as useful as rote memorization. In fact, it’s much better. You’ll have a better sense of when to use a formula and be more accurate in executing it if you understand the math behind it. Let’s look at a concrete case to illustrate. The distance formula is a prime example. It’s ugly…

MagooshSAT_DistanceFormula

…but it actually represents a pretty simple idea. If you have any two points on a graph (on the coordinate plane), you can make a right triangle that connects those two points as the ends of the hypotenuse. That is, you draw a diagonal line between the two points, then a straight horizontal line and a straight vertical line going through each point to make the legs of the triangle.

MagooshSAT_Triangle

Then, since you’re trying to find the length of the hypotenuse, you just use the Pythagorean theorem:

MagooshSAT_PythagoreanTheorem

(Notice that a couple very basic formulas like this one do need to be memorized.) The lengths of those legs are a and b, and the length of the hypotenuse is c.

So let’s find the length of c:

MagooshSAT_LengthofC

And if you’re trying to find the length of the legs (the shorter sides), you just need to know the horizontal distance between the two points, [more math], and the vertical distance between the two points, [more math]. If you replace a and b with those values, voilà: you have the distance formula.

GMAT Grammar Time: The Complete Consort Dancing Together

Need more GMAT tips?

The good news: This is a “dance” you can learn!

The GMAT Verbal section overall tends to focus less on individual words and more on the meanings of whole sentences.  When comparing the GRE vs the GMAT, vocabulary is essential on the GRE, but students need worry considerably less about vocabulary on the GMAT.  If GRE Verbal tests words, GMAT Verbal tests sentences.

The GMAT Sentence Correction expects you to recognize well-constructed sentences.  What is a well-constructed sentence?  The title, a line from the fourth of the Four Quartets by TS Eliot, gives Eliot’s rather fanciful description of a well-constructed sentence.  Let’s be a little more practical.

Of course, good grammar is essential.  The GMAT will expect you to have subjects and verbs agree, to use correct tenses, and to recognize the difference of that vs. which.  Every nugget of grammar has to be correct, but that’s just the start.

By way of analogy, part of a city planner’s job is to make sure every traffic light in a city is working, but getting each individual light working is only part of the challenge.  An effective city planner has to think about “higher level” issues — timing of the lights, patterns of congestions, etc.  How does the whole picture of city traffic, the “complete consort,” fit together?

Similarly, the GMAT expects you to analyze sentences not just at the level of grammar but at the higher levels of syntax and meaning.  Parallelism is a perfect example.  It’s hard to define parallelism precisely because it higher level — we can put individual words in parallel (noun, verbs, adjectives, etc.) or, as is much more typical for the GMAT, we can put entire phrases and clauses in parallel.  If we have structure such as “not only [phrase #1] but also [phrase #2]“, it’s not enough that each individual phrase be free of grammar mistakes —- the two phrases must “match” (e.g. both participial phrases, or both infinitive phrases).  Parallelism is about whether different parts are “dancing together.”

A very different issue of words “dancing together” concerns idioms. How important are idioms for GMAT Sentence Correction?  Very!  Here, we mean idioms in the sense of which words “belong” with each other.  For example, we would say “an ability to do X”, not “an ability for doing X” or “an ability in doing X.”

Higher level issues extend to logical problems, such as misplaced modifiers or pronouns with unclear antecedent.  Finally, the sentence overall must be work rhetorically — it must be unambiguous yet succinct, overall making a direct and powerful statement.  That, indeed, is the “complete consort dancing together”!

Part of achieving a good score on the GMAT entails mastering this hierarchy of sentence-construction skills.  How you learn this stuff?  It’s important to find a tried and true GMAT study schedule, and to avail yourself of the best GMAT material.

It’s important to read high-brow material, such as the Economist magazine.  With good materials and practice, this is a “dance” you can learn!

Not so Nostalgic for the Standardized Test of Yore

Looking for grad school admissions advice?

No longer are your parents waking you up to study or take a test.

In the twilight region of your brain, there is buried a memory. It probably goes something like this: against your will, you woke up very early one Saturday morning to crowd into a room of similarly groggy teenagers. A vaguely authoritarian figure handed out number two pencils and yelled “start” and “stop” at 30-minute intervals.

You emerged from the experience frazzled, probably wondering why you had to take a stupid test that didn’t test what you really knew but seemed intent on tricking you. A few weeks later you got a score and then went on your way, a sour taste in your mouth whenever anyone uttered the letters—SAT.

Now, what seems a lifetime later, another very similar test stands between you and your academic career: the GRE. Like the SAT, you will have reading passages, big vocabulary words, and, of course, answer choices that are designed to trick you. Unlike the SAT, you may have a very different attitude towards education. No longer are your parents waking you up to take a test or telling you when to study (or at least I hope not); you are in charge, and you are set on doing very well on the GRE.

Much of that success depends not just on the size of your vocabulary or your knowledge of integer properties, but on how well you understand how the test is designed. Below are some points to keep in mind.

1. The SAT and the GRE are not exactly the same

The information above may lead you to think that the GRE and the SAT are exactly the same. First off, the GRE is much more difficult (makes sense since it tests knowledge in grad school bound students). And students often find themselves confused with the different scoring. The GRE score range is from 130 to 170 on a math and a verbal section (the GRE doesn’t have a writing section—though, like the SAT, it does have an essay).

 2. Understand why the right answer is right and the wrong answer is wrong

For SAT test takers there is a tendency to want to argue with the answers, especially on the dreaded SAT reading passages. The key is to not fight the correct answer but understand why the test writers consider the right answer and why your original answer is considered incorrect.

3. You must learn vocabulary

In high school you were probably loath (which means reluctant) to study vocabulary. For the GRE, you have to turn your initial revulsion to all things multisyllabic into an all-consuming passion. Think of a GRE word list as your ticket to a good score.

4. How did you do before?

If you did well on the SAT, you should do quite well on the GRE. There is no SAT to GRE score conversion, but unless you spent college unlearning your math and reading skills, your good SAT score should translate into a good GRE score.

If the SATs did you in and sent you sailing in a different direction in life, don’t despair. That’s what this post is for: to galvanize you to approach GRE studying differently from how you approached SAT studying. An average SAT score doesn’t have to translate into a mediocre GRE score. You can overcome the past. So get cracking on those vocabulary flashcards!

I Stink At SAT Math: What Next?

Looking for more SAT tips? Check out our SAT blog posts.

Help! I Stink at SAT Math!

It’s pretty much inevitable that at some point during your SAT, you’re going to look at a problem and think, “Nope. Not happening.”

Or maybe it will be a few moments after, which can be even more frustrating—you work through what seems like the best way to attack a problem, but then after a good minute or so of work you’re still nowhere near an answer and don’t know what you’re even trying to do anymore.

What you do at that point is key, because the SAT is timed, after all. Every moment you spend looking blankly at a question is a moment gone to waste.

That’s part of why SAT math isn’t really like the rest of the math you do in school. One of the most important skills in the math section is knowing when to guess. That’s one thing you don’t really get from math class.

The principle is pretty simple: if you’re just starting to answer a question and you don’t know what to do, spend ~15 seconds exploring (don’t worry too much about the exact time, but realize this step has to be quick). Rework any equations you have. Label any measurements of a figure that you can infer. Write out the first elements in a series or look for other patterns.

And if, after exploring, you don’t know what to do next, don’t go back to square one and re-live your frustration. Instead, look first at whether there are any answer choices you can definitely rule out. Then circle the question in your test book, select a your best guess the answer sheet (this is why ruling out any answer choices you can is so important), and move on to the next question. Remember that every question in a section is worth the same, so it’s key that you give yourself enough time to get right every question that you can get right. Only after you’ve done that should you resume chewing your pencil and loathing that roadblock question.

As a side note, though, if you find yourself getting stuck on SAT math questions often but, at the same time, really think you know all the material that you need to for the test, then you might want to take a stab at the ACT instead. There’s a huge overlap between the tests, but there’s also a pretty subtle difference in SAT vs ACT math: the ACT tends to be a little bit more straightforward, so knowing the material is enough to answer most questions—it’s less often that you need to figure out subtle twists like what the SAT might throw at you.
