Wrong answers In Kaplan's 2400

<p>I think I found some typos in the Kaplan 2400 math section.
Page 228 number 7---- the answer it finds isnt a choice
page 244 number 16 -----------the book finds the value of k and asks for the value of k + n....anyone else have this problem?</p>

<p>And also 19 on page 247</p>

<p>its official....kaplan 2400 sucks</p>

<p>also discovered two mistakes in "cracking the sat 2006". and the editors of this kind of books ought to be exceedingly careful about what they publish. damn.</p>
