Except for a few ACT math lessons, you are almost finished with math!  We just have a few odds and ends to clear up in addition to one major topic: geometry.  The cool thing about the geometry topics is that you started learning them long ago and you just need to remind yourself of some principles about basic shapes.  In addition, there’s some basic trig on the ACT and SAT tests–no big deal, just some things you need to memorize.  Then we’ll wrap up with a couple of truly “miscellaneous” topics that don’t show up very often but they can show up so we’ve included some videos about them too.
