<p>I got 630 on diagnostic from Barron’s, 590 on test 1 and 630 test 2. Just took an official BB test today and got 720. I think I can improve more and get an 800 this Saturday.</p>
<p>^ I got a 600-610 on the Barrons #1 test </p>
<p>gonna take the BB test and see what happens.</p>
<p>@dwarfwarri: What was your raw score? I ended up ommitting a good number of questions on the Barrons test and only had a raw of 22-23/50?</p>
<p>raw score was around 26 or 27 on barron’s</p>
<p>I’m geting around 720 every time on Barons with the occasional 750. I’m pretty confident for the test, hopefully I can get an 800! I need it!</p>
<p>lol waiting for score verification still. CB is so slow 
700s on barron’s. 640 on real thing???
MISTAKE. huge.</p>
<p>I’m getting about 670 usually. Do you think this on Barron’s is good enough for an 800 on test day?</p>
<p>I think you will probably get an 800 if you don’t screw up on test day and perform just as well as you do on practice tests. The official math 2 tests are really a lot easier compared to the barron’s ones that I did. I just use barron’s for reviewing material and also for getting some practice in my weaker areas.
like there was even a question that had csc(2theta)sin(2theta)=
a)1
b)0
c)-1
d)2csc(4theta)
e)2sec(4theta)
which is really straight forward if you know the reciprocal trig stuff.</p>
<p>i took bb test #1 and got a 750, taking #2 tomm my last test before the real test</p>
<p>Wait, how do you do that question that dwarfwarri posted?</p>
<p>It’s equal to sin(2x)/cos(2x) but should I proceed to use the double angle formulas or is this just a simple case of subbing in any value for x?</p>
<p>i got a 770 on BB test #2, but the timing is still a problem for me.</p>
<p>dwarfwarri’s question is easy. csc=1/sin, so the sins cancel out and you have 1.</p>
<p>^oh wow, I read ‘csc’ at ‘sec’ and thought it was the recip of cos…lol, OK thanks. I got a huge scare that I didn’t know how to do it. If anyone has the official tests from the subject test booklet could you post the hardest ones? (like 45-50 or if you don’t mind, 40-50. I would be super helpful for everyone the night before to either go in confident or prep some more).</p>
<p>Thanks!</p>
<p>question 49 and 50 from CB test 1 math 2
49. If matrix A has dimensions m X n and matrix B has dimensions n X p, where m, n and p are distinct positive integers, which of the following statements must be true?
I. The product BA does not exist.
II. The product AB exists and has dimensions m X p.
III. The product AB exists and has dimensions n X n.</p>
<ol>
<li>can’t really post this question since there’s a graph involved. But it shows some points that are labelled, then asks: If w is the complex number shown in the figure above, which of the following points could be -iw?</li>
</ol>
<p>anyone else here verifying your scores?</p>
<p>@dwarfwarri, is the answer to 49 I and II? </p>
<p>And what is ‘w’ on the graph and how would you go about solving that one?</p>
<p>Were there any other particularly challenging ones that you could post?</p>
<p>anyone able to post some challenging ones from the CB math ii tests that we could work on?</p>
<p>^ The following is Question 48 from the Official Practice Tests book:</p>
<p><a href=“http://talk.collegeconfidential.com/sat-subject-tests-preparation/1043302-quick-math-2-question.html[/url]”>http://talk.collegeconfidential.com/sat-subject-tests-preparation/1043302-quick-math-2-question.html</a></p>
<p>I would be utterly grateful to anyone who could provide me with an explanation. :)</p>
<p>^I took a look at your question, but I don’t see how it’s “None”. Maybe CB made a mistake? Check the front of your blue book to see if there is a page of corrections to answers</p>
<p>yea viggy, answer is I and II.
For question 50, there are a set of axes (imaginary) and points placed randomly. I think you just need to review page 142 from Barron’s and you’ll be set for that question. Sorry I wasn’t able to post the whole question up.</p>
<p>Np dwarfwarri. Good luck tomorrow everyone!</p>
