Title: Typos, typos, and imbecilities
Review: There are SO many typos in the answer keys of some of the exercises [I feel that it] render almost all the sample tests useless (unless one goes back question by question to find all the errors, and since one is unlikely to go back to look at a question believed to have been answered correctly, one doesn't actually know how well one has done.) Worse, in the section meant to analyze capabilities, [I feel] it is often assumed that one doesn't know how to do a question -- and hence the only correct answer is to say that one has guessed!As a result, one may be misled to work on a course of study that is unnecessary, and miss the one that is!A shocking piece of work.
Is the review positive or negative?
