Chapter 1- 100%- wasn't difficult at all
Chapter 2- 100%- very frustrating, I couldn't get the one of the questions right, got all but that one.  Finally got it after many, many tries. 
Chapter 3- 100%- very easy
Chapter 4- 100% of the multiple answers but 3 are not graded, but I took there advice on them and changed what I could.
Chapter 5- Ungraded questions but took the advice they gave and did what I could.  They should be right.
Chapter 6- 100%- This was an essay exercise so 12 unanswered but they should all be correct!
Chapter 7- 100%- not difficult at all, when I have my book to help.
Chapters 1-5- Got all the multiple questions right but a few ungraded questions.  They all should be correct since I followed there advice.
Chapters 6-7- 5 ungraded questions, should be 100%.

All these tests didn't take long and weren't too difficult.  It would have been nice to know if I got the ungraded questions right but I followed there advice so most likely I did.  Overall, not too bad.
