Some questions in the practice tests do not have a right answer because of a mistake in either the question or the answer choices. There are mistakes where the answer key differs from the explanation. There are also questions that have glaringly obvious puctuation errors.
Of particular concern, is the math section. The cover of the guide advertises "Extensively revised and updated," and "All new math review." However, is where I found the greatest number of flagrant errors.
I don't know if primary responsibility for these errors rests with the author(s), editor(s), or publisher, but I'm certain most everyone will agree that the quality of educational materials of this nature is everyone's concern.
I have sent a sample of the errors I encountered to the publisher for review. I have also forwarded a copy to the Board of Education in California. Based on the number of (obvious) errors I encountered, I think it safe to assume the actual number of errors, in this particular publication, goes far beyond the 50 "+" question and answer errors I documented.
I am almost through with the math portion of the GED book, and I am so angry. By the time I realized how many errors were in almost every micro-section of the math review, I had already thrown away my receipt. This book is unbelievable. Granted, the portions that are written accurately are thoughtful and mostly easy to follow, but the amount of errors (3 errors on one of the math pages) are incomprehensible. How did this happen? Error after error after error.....I think you get the picture. I am now on page 522, where the "ANSWERS" portion of a chapter review test lists the answer to problem #6 as choice "7." Well, hello, but the choices only number from 1-5. Choice Number 7 doesn't exist!
Barron's wasted my time and my money on this one. The discussion portions are extremely helpful, but need to be backed up with consistantly accurate math problems and answers. If Barron's can go back and fix these errors (and maybe offer the poor saps who bought this version an unconditional money-back return policy, with or without receipt in hand), this would actually be a great book.
Then there were all those typos. Big ole honkin' errors everywhere. So the practice tests were almost worthless. They were also arranged in such a manner that I had to use three bookmarks to refer back and forth after each section. Very annoying, and the book's squat shape wouldn't let the pages stay open by themselves, so I always had to use a hand or a knee or something to anchor them down.
Where the book does give useful information, it doesn't give enough. There was a little section (about a page) on math formulas, which was nice, but what I really needed was a page or two of those little math "tricks"--those shortcuts you learn in high school and promptly forget until the next time you take a math class (which is a looooong time for some of us).
I would have given this book one star, but a) it was better than nothing, and b) there *is* a 3rd edition out, so maybe there's hope.
I have taken all of the GED pretests in this book. That is where I am going to stop. Along with errors, it is my opinion that the passages they give you to read from often do not give ample detail for the questions afterward, and in a few cases none at all. I will give examples upon request via e-mail if anyone would like.
I read approximately 500 pages a week as a pastime, and have been a writer for 13 years- I just didn't get my high school diploma. I still scored well on these tests, as well as can be expected, but have scored significantly higher on other books. I believe this is due to others having questions that better pertain to the information given.
