<p>What is the significance of the focus? Do we need to know it?</p>
<p>I’ve seen it pop up a lot during practice tests, and the answer to the second question is a very resounding (if not obvious) yes.</p>
<p>I got a 750 on the Barron’s diagnostic, but mid/low 600s on the first two practice tests…is that strange, or did other people experience this as well? Btw, in other prep books after taking a couple practice tests I’ve gotten to ~750.</p>
<p>Did 690 on a practice test but I still haven’t reviewed Geometry, numbers, and Data analysis. I have been taking these without a graphing calculator so maybe that is holding me back a bit, but I think now I can focus almost all of my time on Math 2 because I just got 770 Kaplan Physics which takes some studying burden off of that subject.</p>
<p>Has anyone done practice exams from the blue College Board study guide? What did you think? Don’t want to get false security here.</p>
<p>I thought they were easy compared to every other practice test I’ve done. </p>
<p>ya barrons was brutal probs got around a 600 on it and didnt even finish it
got a 740 on the college board test and ended up with a 770 on the may 2014 math 2 test so basically barrons is waaaaay too hard</p>
<p>I can’t seem to break 700 on Barron’s. That’s just where I’ve been staying for the past 2 tests and I only have 3 more.</p>
<p>I plateaued a little bit too. But if you read thoroughly through, you’ll find it helps a lot.</p>
<p>I ended up with a 740 on that last Barron’s test. Hopefully it’ll be a lot better with the actual test.</p>
<p>Barron has 5 practice exams, does each one get easier? DS went from 640 to 740, still has 2 more practice exams left to do. We are encouraged!</p>
<p>To me, I thought they increased in difficulty.</p>
<p>Hey is integral included in the sat math 2?</p>
<p>does anyone have links to practice tests or quetsions? thatd be awesome</p>
<p>Integral- no. </p>
<p>Hey guys. For an 800 on the real test, will 700 on Barron’s do the job?</p>
<p>Can somebody help me on this question? I looked on the back, but the explanation was a bit sketchy. This is from the Barron’s book’s Model 2 Test. </p>
<p>Which of the following is the equation of the circle that has its center at the origin and is tangent to the line with equation 3x - 4y = 10?</p>
<p>I tried to find the y and x intercepts of the equation and then tried to find a radius of that length, but the back had a different answer, and I was wrong… I don’t even think the answer I was trying to find at that time was even on the listed answers. Can anybody help?</p>
<p>@Newdle, first draw the diagram. You’d get a circle, with its center on the origin, and a line perpendicular to it ( tangent) . To find the equation of the circle, we need to find the radius ( which is the distance from origin to the tangent line) , and the center( which is given as (0,0))<br>
There is a formula to find the distance between a line and a point. You can find this formula in Barron’s on page 132, example 1. Using that formula, we get the distance between the center ( origin) and the tangent. This distance is basically the radius. Now substitute in the equation of circle : (x-0)^2 + (y-0)^2 = 2^2</p>
<p>Eh, it just doesn’t sound right to me, though… How can a line, whose slope is not 1 or -1, be equally distant from a circle throughout its entire line? Sorry, I’m pretty clueless .___.</p>
<p>Wait… Can I find the line perpendicular to 3x - 4y = 10 and then use the point they intersect and then determine what that distance is from (x,y) --> sqrt(x^2 + y^2)? I just don’t know if I’m going to have enough time when the real test comes D:! Can you explain me that formula, by the way? I think you were referring to the ax + by + cz + d = 0 and so forth.</p>
<p>I believe that formula is the abs(ax1+by1+c)/rad(a^2+b^2)</p>
<p>I personally do the pythagorean method, but that formula might be useful.</p>
