<p>Where are the answers to the math tips? It seems that all the options are possible for question 1 under Tip 37.</p>
<p>Yes, I was also confused about that question. By reading the answer sheet, it seems like the question is erroneously phrased. Instead of a<b it should say a<b<b+3 because otherwise it’s indeed impossible to answer.</p>
<p>Questions like this one make this book pretty worthless, IMHO</p>
<p>^Agreed. If you’re going to make a test preparation book, or a mock exam of any kind, you better make sure you revise it well for math errors, ambiguous wording, etc.</p>
