I studied for the TEA with this book and almost walked out of the test. I read the book cover to cover and walked in feeling very confident. The joke was on me! When I got to the math part, after 4 questions, I seriously considered walking out. I reconsidered and finished the test. Luckily, I have a strong enough background that I passed. A friend of mine who took it at the same time (and studied the same book) was not as fortunate. I definitely do NOT recommend this book! The other sections were not bad, but the math?
