<p>I couldn’t find a thread like this anywhere else, so I decided to start it. Title is self explanatory - If you notice any typos in Dr. Chung’s SAT Math Book, list them here.</p>
<p>Idk about typos but do. Noe if the book is helpful</p>

<p>Does it improve ur sat math score…I currently hv a 650…can I get a 750 with the book</p>

<p>It should help you. Not sure how it helped but since it was all I used, it clearly did. I had a 690 Math, after studying it not even overload I got a 740… I made 2 silly mistakes on easy questions, I should have gotten a 790. So it definately helped me. Then there is always the chance that the June test was just easier / I got more careful. Not necessarily worth the 28 dolalrs in my opinion, but I procrastinated and only read the tips, and did 1 practice test</p>
<p>Hmm… I’m planning on getting an SAT math book, I have a 600 (practice test) and I would like to raise it (to over 700). Would Grubers Mathbook or Dr.Chungs be better?</p>
<p>Dr. Chung’s is a lot harder and it has 20 practice tests, so probably that. i have both but gruber’s sat workbook only have 5 tests.</p>
<p>Anybody want to link me to this Dr. Chung’s Book or maybe give a description?</p>
<p>[Amazon.com:</a> Dr. John Chung’s SAT Math (9781439234976): John Chung: Books](<a href=“http://www.amazon.com/Dr-John-Chungs-SAT-Math/dp/1439234973/ref=sr_1_1?ie=UTF8&qid=1310258529&sr=8-1]Amazon.com:”>http://www.amazon.com/Dr-John-Chungs-SAT-Math/dp/1439234973/ref=sr_1_1?ie=UTF8&qid=1310258529&sr=8-1)</p>
<p>It looks very interesting.</p>
<p>So, my question is how exactly do i use the Dr. Chungs SAT math book?
What i’m thinking about doing is taking the practice tests that he gives, and then going over the question, especially the wrong ones, and then looking at his 20 perfect tips according to what question i get wrong on the practice test because I don’t think it would be as beneficial to me if I were to go in order and review all the tips, and then take the practice tests because I wont be as focused, and basically i’ll start thinking about other things because it’s so boring. So what do you guys think??</p>
<p>By the way, my math score is around 650-700… so not great, but my goal is to get an 800, and I think that, based on the reviews, that this book will help me achieve that.</p>
<p>I am thinking about purchasing this book because my score in math varies from a 670-710.
I just have several questions about this book.</p>
<ol>
<li>Is it really effective?</li>
<li>Does it resemble the SAT’s math or is it another one of those books?</li>
<li>If it is effective, would it work if I did all of the questions within 1-2 months?</li>
<li>Is it better than Gruber’s?</li>
</ol>
<p>bumppp</p>
<p>I want to know too cause I’m deciding between Grubers and Dr. Chungs</p>
<p>Dr Chung has more practice tests, and had better overall ratings then Gruber on most sites like Amazons. </p>
<p>However Gruber is universally accepted by College Confidential as a math-machine. </p>
<p>Idk. Gruber has everything you need mostly, so I dont think you need Dr Chung in my opinion.</p>
<p>Since you’re already scoring pretty high, then get Chung’s. If you’re scoring lower, get Gruber’s.</p>
<p>chung has 20 practice tests while gruber’s has like 5. chung’s offers a lot more practice and i would say the 50 tips at the beginning are helpful. it is harder than grubers imho</p>
<p>bump…bump anyone??</p>
<p>These questions are from the Dr. John Chungs SAT Math Book, but I don’t really understand his explanation to these question.
All of these questions are from Test 1 section 3.</p>
<h1>3- (it has a figure but I cant draw it) In the figure above, angle BAC=30 degrees, angle BCD=60 degrees, and the length of AC is 4. What is the area of triangle ABC?</h1>
<p>A. 4
B.4 SQUARE ROOT 3
C. 8
D. 8 SQUARE ROOT 3
E. 16</p>
<p>So what he does is he then says that CD is 2 and that DB is 2 square root 3. So then he does 5 square root 3 times 2 to give him 10 square root 3 for the length of AD and then he times it by the height which is 2 square root 3 and then divided the whole top by 2.
Which gives him the answer of B. 4 square root 3</p>
<p>Angle ACB = 180 -60 = 120
Angle ABC = 180 – (120 + 30 ) = 30
So triangle ABC is an isosceles triangle, which means 2 sides must be equal. So BC also equals 4</p>
<p>Triangle BCD is a 30-60-90 triangle. So that means side DB = 2 root 3.
Just use the formula for the area of a triangle which 1/2bh</p>
<p>½ * 4 * 2 root 3 = 4 root 3 which is B</p>
<p>I hope this is clear, if you need anymore help just ask</p>
<p>I get it now thanks alot… so basically to answer this question you have to know that in an isosceles triangle 2 sides are equal (Which i didnt really pay attention to) and after that you have to fill in the lengths based on the information that it is a 30-60-90 triangle. Right??
Anyways…thanks
Also, can u help me with my other question
thanks again</p>
<p>These questions are from the Dr. John Chungs SAT Math Book, but I don’t really understand his explanation to these question.
All of these questions are from Test 1 section 3.</p>
<h1>4 - (There is figure but I cant draw it) In the figure above, a circle is tangent to the side of equilateral triangle PQR and the radius r equals 5. What is the perimeter of triangle PQR?</h1>
<p>A. 20
B. 30
C. 30 square root 3
D. 35
E. 40 square root 2</p>
<p>So what he does is he draws a line from the center of the circle to P and creates a right triangle. He then uses the 30-60-90 triangle to make PS 5 square root 3 making PR become 10 square root 3. He then multiplies 10 square root by 3 to give the answer of 30 square root 3. So my question is, how did he know that it would create a 30-60-90 triangle and not any other triangle, even maybe a 45-45-90 triangle?</p>
