Have you seen this book for the General math yet? I'm not particularly intuitive when it comes to math and I need things broken down in order for me to understand them fully. I really appreciate how the author of this series takes the time to explain how to solve each type of math problem on the test. I found it a *lot* better than the ARRL manual's explanation!
I have this and would definitely recommend it!
