<p>For Model Test 3, question 32, in the explanations, it says that you substitute -1 as x to find the remainder but it substituted 1 in one of them and then gets -20 instead of -12.
Is this a misprint or am I doing something wrong?</p>
<p>I’ve already seen a few typos so you’re probably right.</p>
<p>There are so many typos throughout the book that, as a rule of thumb, you should trust your own judgment over what the book tells you.</p>
<p>I’ve just taken the same exact practice test. It is a typo; the correct answer is -12.</p>
