Title: The typos are useful!
Review: Overall the book really is immensely useful for studying for the GED.But...the typos are annoying. Incorrect answer numbers in the answer key waste a lot of time and cause one to question their sanity after 20 attempts to match the answer number given. The following explanation pages usually,(not always), have the right answer number. But, sometimes the explanation backs up your 'wrong' choice and not the answer given. Sometimes explanations of answers are sooo vague they are frustrating. Sometimes 'facts' contradict themselves in different places; sometimes 'facts' contradict conventional usage. Best to check with other references when it gets confusing.It does keep one thinking, and digging for information, though. Maybe that is the purpose. If so, it does make for great discussions. and discussions are great for learning, so, I do recommend it.
