SAT - New Math Formulas

SAT has always provided a math formula chart at the beginning of every math section. However, there are quite a few new formulas that students need to memorize in order to master the math sections.

A= P (1 + r) ^ t
The amount of money accumulated over t years can be calculated by raising (1 + r) to the t power where r represents the interest rate. Once this amount has been calculated then it is multiplied by P the amount of money initially invested.
Of course, this type of problem will be on the calculator portion of the math test.

If they ask for the continuously compounded interest, the formula used will be Pe^rt.

Half Life Decay Equation is f(t) = a .5 ^ t/h
a = initial amount
t = time (total)
h = time it takes for half the sample to decay 
t & h must be expressed in the same units

Quadratic formula is now required: -b + and - sqrt b^2 - 4ac all divided by 2a

Sum of solutions for a quadratic equation is -b/a .

The ACT vs. The SAT - Which Should You Take?

There a few things that you need to consider before you make your decision. To get started you need to look at your three PSAT scores (critical reading, math and writing) and your Selection Index (SI), which is the sum of all three PSAT sections. You then take your SI and add a zero to the end to make it four digits.

The general rule is that if your total PSAT score is below 1500 and your math score is strong, then you will want to take the ACT. If your total PSAT score is over 1500 and your score in language arts is strong, then you would prepare to take the SAT.

There are some exceptions, though. Let’s say your total PSAT score is below 1500, but your math score is low, then you may want to look into taking the SAT. If your total PSAT score is over 1500, but your critical reading score is low, then you may want to consider taking the ACT.

Most will agree that the ACT is generally easier overall. It is also usually recommended for those students who suffer from testing anxiety. It is important to note that you are not penalized for wrong answers or guessing when taking the ACT test.

Besides looking at your academic strengths, you will also want to consider college preferences. If a school on your list prefers one test over the other by accepting an extremely low score on one test versus the other test then it’s essential for you to focus your efforts accordingly. If you haven’t narrowed your college search, then you’ll want to focus on the test that will allow you to excel most & accentuate your skills.

PSAT & SAT Test Formats to Change

Stay tuned for the upcoming announcement by College Board on March 5, 2014. Education professionals speculate a new science section will be added to the PSAT and SAT test formats. 

2012 PSAT Scores Released

College Board has released the 2012 PSAT test scores. Please check with your counselor for your individual test results.
 
Did you know? Your PSAT score is a good indication which test path you should pursue for admittance to college.
 
PSAT 150 (National Average) equates to a SAT 1500 (National Average) which equates to an ACT 21 (National Average).
 
Typically, someone who is an excellent reader and has developed a verbose vocabulary will perform better on a SAT test. On the other hand, someone who scores high on the math section will typically fair better on an ACT test.
