Query: A frustrating book to learn from

This book is awful. My professors despise it and are switching next year. I skipped a year of Arabic and came into a class that was in the middle of this book. What a headache trying to figure out the format of the book. As far as the vocab, it is pretty irrelevant to someone who wants to learn to have an actual conversation in Arabic. I know all kinds of words for business and can tell you about Egypt's economic independence upon the Nile, but I have no idea how to ask where the restroom is. The dual for any form of verb is simply not listed. You don't even learn the numbers until half way through the book!
