<p>All I can say is that this is not an Official SAT test. I know that question #8 in Section 1 is direct copy of an official SAT question. </p>

<p>It is based on the following official SAT question
If (x+y)/(a-b) = 2/3, then (9x+9y)/(10a-10b)=
A) 9/10
B) 20/23
C) 20/27
D) 2/3
E) 3/5</p>

<p>You will see the similarity.</p>

<p>Overall, this is a good example of how to waste your prep time. While many of these questions are reasonable sat-ish questions, there are some real klunkers in there – weirdly worded, wrong level of difficulty for where they are placed in the section or just not of a quality that matches the SAT. And unless you have done a lot of practice with real SAT problems, when you have difficulty with one of these, you won’t be able to tell if it’s your fault or theirs.</p>
