Reddit mentions of Workbook to Accompany The Complete Musician: Workbook 1: Writing and Analysis

You can also supplement it with any music theory textbook. Most people recommend Laitz "The Complete Musician," but there are plenty of others. You can find the pdfs online if you search around a bit and then buy a workbook for an old edition for about 5 dollars on amazon. That'll give you ~2 years worth of college music theory with exercises to master whatever you want. These videos get about 2/3 of the way through any of the books and I think he's making more this summer. This is another professor that gets a little further in the curriculum, but his lectures aren't as well done (they're dry) as the first link.

I have this one (http://www.amazon.com/Workbook-Accompany-The-Complete-Musician/dp/0199742790). Looks like it's the 3rd edition.
