<p>I’ve heard that past tests aren’t that generous though? That would mean my raw score is at most 70.</p>

<p>I’ve heard you can miss 4ish and still get an 800, so yeah.</p>

<p>I think I misread the salt question to say what would happen if you put an animal cell in a .9% salt solution.</p>

<p>if you put a cell in .9% salt solution, it would be isotonic, so there would be no net movement of water. </p>

<p>according to Princeton Review, a raw score of 70 is around 730.</p>

<p>Yeah, I put that there would be no net movement of water. Is two wrong likely an 800?</p>

<p>Barron’s says 70 = 770, but I don’t want to be too hopeful.</p>

<p>Kaplan’s says 770. Let’s take the average and say 750ish.</p>

<p>I’ll take 750 anyday, thanks for your help csquare!</p>

<p>I’m hoping for a 700+, although I’m going to retake it next month (I’m not so sure I got at least 700).</p>

<p>I want 800</p>

<p>i’m pretty sure the cell in the 0.9 solution was swell and burst.</p>

<p>i’m pretty sure i got at least 10 questions wrong… would it be a good idea to cancel? i’m about 100% sure that i will retake anyway since i was aiming for a 750+ :frowning: … or should i keep my score just incase i end up doing worse on the retake?</p>

<p>The nails/claws question didn’t involve birds having claws? I guessed that…</p>

<p>i think there should really be no debate on the colorblind son problem. im 110% sure it’s 1/4 theres a problem exactly like it in my kaplan book, and the answer is 1/4. if ppl want i can write out their question word for word and the explanation they gave, but i hope youll take it on faith, & to just summarize:</p>

<p>first, to have a son, that’s 50% likely. also, because the mom was just a carrier, she has one XA and one Xa, so in giving the son an X, theres a 50% chance hell be colorblind. so: 1/2 x 1/2 = 1/4.</p>

<p>I don’t think the debate is on the actual answer, but what the question asked for. (I didn’t take the test though, so not 100% sure)</p>

<p>Y’all seem tied up between whether the question asked “What is the probability that they will have a colorblind son?” or “What is the probability that the son will be colorblind?”</p>

<p>From reading this thread, it seems that:</p>

<p>Kaplan says raw score 70= 770
Barrons says raw score 70=770
Princeton review says raw score 70= …730?</p>

<p>Why is there such a big margin? And could any SAT II veterans tell us what kind of curve to expect on this test? Most people are saying this test was harder, although some are saying it was on par with other tests. How many questions do you predict we can miss for a 750? For a 700? 650?</p>

<p>Well… I took the practice SAT 2 from the Real SAT Subject Tests book; their curve was 73 was still an 800, and I got a 77.</p>

<p>This test? I’m currently predicting around a 75ish. I omitted 1 and missed 3 for sure.</p>

<p>So, I declare that this test was harder. XD</p>

<p>Mandizz - the big difference is between the difficulty level of the books. I have both Kaplan and Princeton Review, and Kaplan is WAY harder. In fact, it is unrealistic. Princeton Review is A LOT easier, and more like the test we took on saturday. I believe it better simulates the actual thing. Therefore, I’m going with PR’s curve.</p>

<p>I agree. Kaplan is a lot more fact-based and remembering concepts. PR and Saturday’s test were more interpreting charts/graphs, applying concepts.</p>

<p>does that mean our curve is going to suck :(</p>
