Despite what many high school students believe, you need to know relatively few formulas for the New SAT Math section. The reason why there are so few formulas necessary for SAT Math is that the SAT is meant to test your reasoning skills more than your ability to memorize though in some cases, of course, memorization is necessary.
There are always multiple avenues to the solution of a problem, and I teach my students how to take a consistent, accurate approach that utilizes a minimum of formulas and takes the path of least resistance to each answer. Usually, this involves solving the problem differently than you would in math class, stressing technique and common sense over pure memorization.
Take, for example, the distance formula. Well, no worries, because the distance formula is completely useless on the SAT--and it's just a rearranged Pythagorean theorem anyway.
The Pythagorean theorem is easier, more basic, and less prone to mistakes than the distance formula. So unless you are a whiz at the distance formula and never make careless mistakes on math questions, I would stick with the advice of Mr.
That being said, there are still a few things you must know by heart on test day. Also know what the discriminant is.
If the discriminant is ZERO, then there is 1 real root. Mean is the same as average. Median is the number in the middle after rearranging from low to high. In the case that the list has no true middle because it has an even number of terms, find the average of the middle two.
Multiple modes are possible if there is a tie for greatest frequency: Integers are whole numbers, including zero and negative whole numbers. Think of them as hash marks on the number line. Remember that -3 is less than -2, not the other way around sounds simple but is a common mistake.
Prime numbers are positive integers that are only divisible by themselves and the number 1.
Be able to list all the primes you between 1 and 50…remember that 1 is not a prime and there are no negative primes. By the way, 51 is not prime…that question actually showed up on a recent SAT.
What, you forgot your times tables for 17? The prime factorization of 18, for example, is 3 x 3 x 2. These are particular types of Right Triangles that just happen to have exact integers as sides.
The SAT loves to use them, so know them by heart and save yourself the trouble of calculating all those roots. Here are the ones they use: Digits are to numbers what letters are to words.
There are only 10 possible digits, 0 through 9.SAT Test Dates and Registration The SAT is a nationally administered, standardized paper-and-pencil test that helps colleges evaluate candidates.
Generally, you'll take the SAT for the first time in the spring of your junior year, and scores typically come back in . The SAT or the Scholastic Aptitude Test is a standardized exam that evaluates the mathematical, writing and reading prowess of a candidate for admissions to colleges in the US and Canada.
I ordered and have been using the Barron's SAT II Physics prep book to study for an upcoming test. I've found the book to contain all the information necessary to do well on the test - that's a plus - unfortunately, though, the information is organized in an overwhelming fashion.
Introduced in , its name and scoring have changed several times; originally called the Scholastic Aptitude Test, it was later called the Scholastic Assessment Test, then the SAT I: Reasoning Test, then the SAT Reasoning Test, Two section scores result from taking the SAT: Evidence-Based Reading and Writing, and Math.
Section. The following is an abbreviation of the chapter on this topic from my book, College Prep , Second Edition. The most stress-inducing part of the college preparation process is college entrance exams.
