<p>why not finish it AND use chungs…if you really want that score, wouldn’t you be willing to do whatever to do that?</p>
<p>Herozero summed it up perfectly.</p>
<p>Hi, I’m currently struggling with the math section of the SAT. My scores are around the low 600’s and I have both Gruber’s and Dr Chung’s. I’ve worked through most of Gruber’s book already and I moved onto Dr Chung’s book a few days ago. However, I find that I get stuck on quite a few questions but I seem to understand them when I look at his solutions. I don’t really know how much my score has improved after Gruber’s because I was advised to work through Chung’s first before taking a practice test. Do you think my method is effective for improving my math score? Should I, as xiggi advised, work through all of the BB math practice tests first before moving onto Dr Chung’s? And finally, is learning from the solution less effective than trying to figure it out yourself (but spending ageeesss on the question)?
Thanks in advance!</p>
<p>HELLO! anyone with dr. chung’s book, do you know how to solve question #13 on practice test 1 section 7 on page 112??</p>
<p>Tip 2, question 2: I don’t understand the explanation. I’m with him as far as the similar triangles, the ratios of the lengths of the triangles, and the ratio of the areas, but I don’t understand His usage of the variable k. Thanks in advance.</p>
<p>Page 53, 1st Example of Tip 31. It should be 12000 to 15000 students.
Page 62, 1st exercise. I guess it should say “if a<b<b+3” because otherwise the answer makes no sense.</p>
<p>Test 5, section 7, question 7. II must be “a must equal 5”, not 0.</p>
<p>Page 204, question 18. Why the answer is not E?? </p>
<p>In the xy-plane, the equation of the line L is y=-3/5x+4. If line M is a reflection of the line L over the x-axis, what is the equation of line M?</p>
<p>In the book the correct answer is 3/5x-4, but shouldn’t the slope be 5/3? The reflection is perpendicular to the original line.</p>
<p>Reflecting a line in the x-axis does not give a perpendicular line unless the original line has a slope of 1 or -1.</p>
<p>Oh, then it’s another gap in my knowledge. Thanks for the answer :)</p>
<p>page 233, test 7, section 7, question 8, a) should be 30 without a minus.</p>
