Continuing with the Art of Problem Solving: Introduction to Algebra book that I'm studying with the help of zedzed (see here for an explanation):

Chapters 8 and 9 (I knew most of these chapters already, so I only did the hard problems; section 9.5 I didn't know so I did all the problems for that and graded it separately):

• Chapter 8: 3 out of 6 correct (50%)
• Chapter 9 except section 9.5: 5.5 out of 7 correct (79%)
• Section 9.5: 96% out of 138 possible

Chapter 10: 95 out of 123 possible

Chapter 11: 95.5 out of 118 possible

Also, to help my studying I asked my wife to use Windows parental controls to lock my computer entirely during my main study period. Works wonders!
