<p>Barrons I’m always at low 700s…it’s driving me nuts because I can figure out most of the problems, I just don’t have enough time. Also, I never learned matrices so that sucks for me. </p>
<p>@hagzzz
In that case:
300 = 600 * e^(-t/1000)
0.5 = e^(-t/1000)
ln (1/2) = -t/1000
-1000<em>ln(1/2)=t
-1000</em>ln(2^-1) = t
bring the -1 down
1000*ln(2)=t
ln(2) is around 0.693, thus t=693</p>
<p>I can’t look at these problems with this kind of format… </p>
<p>Kinda worried because I just scored a 660 on the first Barron’s diagnostic test. Sigh.</p>
<p>Are the SAT Math 2 Practice tests in the Official SAT book a good indication of how you will do on the tests? Because I am going to start studying today and I took a pre-test, and I got an 800 (missed 6) on practice test 1, but when I glanced through practice test 2, there were some interesting, hard-to-remember stuff on there. (I haven’t taken Pre-Calculus/Trig in a little bit over a year, and I took Calculus the first semester 
)</p>
<p>Well, what book do you use?</p>
<p>@cjwu382 the official sat blue book</p>
<p>@Newdle, <a href=“http://s3.amazonaws.com/illustrativemathematics/images/000/001/081/large/tang1_da02ab8f9928cf295c6d13e3fdc731f4.jpg?1341857748”>http://s3.amazonaws.com/illustrativemathematics/images/000/001/081/large/tang1_da02ab8f9928cf295c6d13e3fdc731f4.jpg?1341857748</a>. See the image. The line L here has the equation 3x-4y = 10. And that is the circle. Now you have to find the distance between O and the line L. For that , you use the formula abs(ax1+by1+c)/root of (a^2+b^2)</p>
<p>Have any of you all found any practice tests online which are somewhat more realistic to the test than the Barron’s ones? Looks like the SparkNotes ones have been removed and there really don’t seem to be that many other resources for review.</p>
<p>Any1 here tried the questions from xtremepapers ( arco )?
i managed to get an average of 700 ( 620,690,740,780 ) from barron, but i can only finished 20 questions from arco in 60 minutes, that’s so humiliating T^T</p>
<p>Are miscellaneous equations on the test? I’m in Trig now and have not learned it. Also matrices, also conic, polar, parametric, …the list goes on! :(( :(( </p>
<p>this thread is the official for sat 2 math level 1 right</p>
<p>^^ nahh “SAT Math Level II”</p>
<p>@PoisonIvy20, I don’t know what you mean by miscellaneous equations but things like trigonometric functions, logarithmic functions, exponential functions, and polynomials are all on the test. Matrices are occasionally on the test, but really all you need to know is matrix operations (addition, subtraction), finding a 2X2 determinant, and finding determinants and inverses on your calculator. Polar is also occasionally on the test, but mostly only in the context of converting between polar and rectangular form and finding moduli. Conic sections and parametric, apparently, are rarely on the test (although in the case of conic sections they do test things like ellipses, hyperbolae, parabolae, and circles, just not in the context of a cone.)</p>
<p>So I know Barrons is supposed to be harder than the real thing, but I’ve taken 3 of its practice tests now and the most I’ve gotten is a 700. Plus I’ve always had to skip the last 5 or so because of time constraints (and even counting the ones I had to skip, if I included those in the score, my total score will jump by 10 points). Do you think I’ll reach my goal of 760+ on the actual thing? </p>
<p>@kirstr, I personally think McGraw Hill and PR are quite realistic, McGraw Hill is a little easier than the actual test and it is available through a torrent on the internet. </p>
<p>Can you guys post a couple of links up for practice exams? </p>
<p>I’m having such a hard time juggling my time between finals and subject tests… I have taken the past two weeks to work through the book and I’m almost done (got 620 on Barron’s diagnostic test… yikes). I’m just hoping for above a 700. Is it doable? I’m planning on doing every single practice test either tomorrow or Friday after my finals (ugh). I’m in precalculus now and my final for that is on Friday so a lot of it overlaps but stuff like matrices and polar coordinates not so much. Any tips? I just want that 700+!</p>
<p>Hi @constantstress, you should be fine. I’m also doing the Barrons book. My advice is to read the review material in the book and do exercises before cramming in practice tests. Simply taking these tests only helps to certain point.</p>

Its like r= modulus |(ax1+by1-c)/radical(a^2 + b^2)|
Where x1 and y1 are the co-ordinates of the center of circle and a and b are from the line equation and c is constant in that line equation 
apply you get radius and eq of cirle becomes x^2 + y^2 = r^2 if circle has center at origin and you know the eq if it is not at origin</p>
