Query: 7th edition with a new cover.

This reference manual is still by far the best reference for the PE test. However, the 8th edition is being marketed as an updated manual designed for the new breadth-and-depth format of the exam. I have the 7th edition and have found that the problems are no way representative of test problems, so i jumped at the chance to purchase the 8th edition. I see absolutely no difference between the 2 editions. DON'T BE FOOLED!!! If you have the 7th edition, do not purchase this book thinking it will be a better reference or you will also be left scratching your head in wonder.
