Question on Wiritng Error ID & Princeton Review

<p>I (told) my English teacher that (the best part) of the novel was (where) the antagonist finally realized the error of (his ways). (No errors)</p>

<p>According to the Princeton Review book the answer is (where). Does anyone have any idea why?</p>

<p>What does everyone think about the Princenton Review anyways?
I find it even tricker and confusing than the actual test… The practice tests in that book totally discouraged me… I got almost half of the Qs in the CR worng… I scored much better when i took the blue book tests about a month ago…
I don’t know if it’s me going crazy, or if it’s just the book…
Unfortunately i’ve taken all the practice tests from the blue book aldready… So there’s no way of figuring out what’s going wrong here :((</p>

<p>I think it should read with “when”.</p>
