<p>How realistic is Princeton Review to the real test?
I got a 34.5/50. (omitted 13 and 2 wrong) When I graded it I found out that I did a lot better on numbers 35-50 than I did on numbers 20-34. Princeton Review said I got a 710/720, a good starting point. All the old algebra II stuff + the wording brought my score down.</p>
<p>You think if I read the PR book + 1-2 more practice tests I could get it over 750?</p>
<p>Say guys, does anybody have a list of these random topics that might show up on the real test? Like Standard Deviation and stuff. I remember seeing a list somewhere here, but finding that thread again would be a pain.</p>
<p>I took a Kaplan test last night and Standard Deviation showed up, so it would be safe to learn it</p>
<p>Do we need to know weird formulas like the area of a Hexagon? :/</p>
<p>Just write down all formulas in a calculator. That’s what I’m gonna do.</p>
<p>Oh and from Barron’s the equation for the area of a sector is 0.5(r^2)(angle)… but does this equation only work when the angle is given in radians?</p>
<p>*edit does this also apply to the Barron’s length of arc equation r(angle)? </p>
<p>Because whenever I use degrees it isn’t working out too well :[</p>
<p>Nevermind I think I just answered my own question… because degrees aren’t given in fraction form already while radians are 
Silly me</p>
<p>What would they ask about standard deviation or eccentricity?</p>
<p>I don’t think eccentricity is on the test, but for standard deviation it was something like, “Here are the mean, median, and standard dev. If each number in the set is multiplied by 3 which ones change?” And then the choices would be in the “I and II” format</p>
<p>Do you guys have any recommendations on approaching probability questions?</p>
<p>f*** probability, weakest point</p>
<p>Same here high five!</p>
<p>You should be able to derive this through triangles and other knowledge.</p>
<p>
</p>
<p>You can just convert radians to angles 180/Pi (360/2Pi).</p>
<p>ex) Pi/4 * 180/Pi = 180/4 = 45 degress</p>
<p>Probability kills me as well. Btw, I’m using an older version of Barrons (7th edition), and the percentage of what’s covered on the test is kind of off when I compare it to the CB website (e.g. algebra 18%). I’ve already gone through a 2009 PR copy and I was wondering if this is ok? I don’t want to be studying the wrong stuff And are derivatives on this test? Because I think Barron’s lightly covers that topic.</p>
<p>So guys, ranks the practice tests and real test in difficulty.
Barron’s
Pricenton Review
CB
Sparknotes
Real Test</p>
<p>example: CB<Real Test<Princeton Review< Sparknotes<Barron’s</p>
<p>I think it’s something along the lines of CB < Real Test < Sparknotes < Princeton Review < Barron’s.</p>
<p>Does anyone know any sites I could go to cram sat ii probability in 3 days? </p>
<p>This site is good for a fact/formulas/cheat sheet(pdf):
[SAT</a> Math Facts and Formulas](<a href=“http://www.erikthered.com/tutor]SAT”>SAT Math Facts and Formulas)</p>
<p>The probability tested on the SAT Math IIC is pretty simple. I would just go over it on Sparknotes and then do as much practice problems as possible. Practice makes perfect!</p>
<p>Can someone give me a brief explanation of linear regression? That would be sooooo helpful :D</p>
