BOB-- Where are we

Well, what i have learned? UM.......
In Chapter 1 I only understand a little part of it, baceuse it's most gr12 stuff which i haven't learned yet.
For Chapter2 I still didn't get it, I was even more confused with all the graphing stuff. The beging part seems to be easy then it become more more harder.
Chapter3 becomes a little bit easier than before so I think I did it better than before.
For this Chapter I find fine but the ends were kind of hard!
The end. ^_^
