<p>Have you tried a Sparknotes test? Barron’s is way harder than the real thing. Sparknotes should give you a more accurate prediction of your mark on the real test, as it’s very similar to it.</p>
<p>I don’t know if linear regression is even on the test, anyone who already took it, please verify.<br>
But to do it, just use your calculator. With TI83+ or higher, I think it’s STAT, CALC, and then you just pick the kind of regression curve you want. I think the LinRegTTest function also works, but I’ve never used it…
For eccentricity: e = (distance between foci)/(length of major axis), the closer to zero it is, the more like a circle the ellipse is
Standard deviation - again, is this even on the test? Please verify.<br>
Use your calculator: go to the catalogue (2nd 0), then pick stdDev and enter values like this: stdDev ({1, 2, 3, 4, 5, 6}) and hit enter. I think there’s another way to do it with stat, list, vars/yvars, but I don’t quite remember the procedure.</p>
<p>For those of you freaking out over Barron’s, don’t worry. For the most part, Barron’s is way more difficult than the actual exam (basing this off of what others have said and previous experience with their AP exam books). I should probably take my own advice because I’m getting 730-740 on the Barron’s and I’M freaking out. Need to go take some Sparknotes to boost my confidence. I’d like to know whether the actual test is easier/harder than PR and Sparknotes. I’m hoping that it’s easier P:</p>
<p>@strawberries21, I think standard deviation is covered, but barely. PR had questions involving mean/median/mode with standard deviation, but I don’t think anything beyond the basic concept will be on the test (although I’m taking it tomorrow for the first time, so I wouldn’t know xP)</p>
<p>I made so many stupid mistakes on the two collegeboard tests… got 730 and 750 
I just took the last 2 sparknotes tests and got 780 and 770, what should I do now? Just review questions? Maybe with a little luck tomorrow I can pull an 800 :D</p>
<p>That is strange, Collegeboard is alot easier than sparknotes.</p>
<p>It is kind of weird… but if I counted out all of the really really stupid mistakes I made on those tests… it would add up to 790s Hopefully I’ll have some adrenaline tomorrow that’ll keep me alert</p>
<p>That is the experience I had, I pulled off a 790 and 800 on the CB practice tests with 10 minutes left at the end, while on the real thing I finished with 20 minutes left and had time to redo the first 25 problems.</p>
<p>Haha I keep telling myself “I’m ready” over and over, and it gets my adrenaline going just sitting here D:</p>
<p>Got 2 790s on the released Math Tests </p>
<p>Hopefully by some miracle I’ll somehow be able to pull off an 800 tomorrow, though I’m not expecting one anymore :/</p>
<p>You’re gonna get an 800, count on it :D</p>
<p>Are the SAT practice ones much much easier?
I got 800s on both easily, and 690 on sparknotes…</p>
<p>are there any programs like the MLT GOld and the SAT2 DOJO for the ti89? i need some programs for my ti89</p>
<p>Where can I find some released questions form previous Sat II math tests?
And my practice scores have been ranging from 710-790. They vary a LOT. Ive been doing Princeton, barrons and sparknotes. I really wanna get an 800 but Idk if I can. Is the curve low? What was the curve for the may one?
And does anyone know where I can find a thread on this college confidential talking about the may sat II math II. I found for bio but not for math.</p>
<p>WHATS THE CURVE? SOMEONE TELL ME PLEASEE THE TEST IS TOMORROW! I miss like on average around 12 questions and I just wanna know what my score would be.</p>
<p>^ That would probably put you somewhere around 720-740.</p>
<p>What would a raw score of 40 usually be?</p>
<p>@hopter, according to sparknotes (same as PR I think), that would be a 770.</p>
<p>So what about ellipses do I need to know?</p>
<p>Just foci and major/minor axis? (and vertex)</p>
<p>^ yea. Foci, which axis is major/minor, length of major/minor axis, vertex, basic things like that. I don’t think eccentricity/latus rectum is on the test.</p>
<p>can anyone explain the how to find the foci and vertex for ellipses?</p>
