Thanks for all of your input! It is really helpful.
The test he took was the actual placement test for the school's curriculum. It was on the computer, and it kept asking more questions as he continued to pick the correct answers. (It was multiple choice.)
From what I saw, the test seemed to have maybe five questions on every topic. Five multiplication, five division, on up to five multiple-step algebra equations. So it definitely wasn't totally comprehensive. It took maybe an hour and a half or so.
The school is an online public school/homeschool, so it is completely self-paced. I think filling in the gaps wouldn't be too big of an issue, I just wonder if there will be so many gaps that starting with pre-algebra makes more sense. As I mentioned before, I can't quite remember what exactly was in pre-algebra because I took it more years ago than I would like to calculate (yikes!).
OK, I'm going to keep thinking about this...
Thanks again!
