NES Highschool Mathematics 304 Teacher Certification Test Prep Study Guide (NES (1)) First Edition, New edition

This particular study guide should be an embarrassment for XAMonline, unless all their study guides are as bad. It is so poorly edited that if you did not know enough to recognize errors in this first edition printing (2011), you could easily get lost and frustrated. Some of the atrocious examples include: "...since g(-x) does not equal g(-x)...", or in a table for metric to English conversions "16 ounces is 1 pound", or "16 ounces = 36 inches." In the first 100 pages I have found over 50 errors that are pure carelessness. If I were Sharon Wynne, the namesake for developing these books, I would be ashamed.

There are many incorrect answers in the answer key. Very disappointing.

Several typos. Did not explain things well. Did not address specifics of the test, for example the type of calculator and the settings for the calculator.

This study guide wasn't the greatest, but it helped. It was a much better alternative to the study guide made by the the actual test maker. It covered all the content with explanations, examples, and a practice test as well. I was able to past the test after quickly reading through the book in about 3 full days. The biggest issue with this book is that it was poorly edited, as there are frequent errors, but if you can get over that fact, it was at the end of the day helpful.
