I'm going to have to call the place, I don't see geometry unless it's blended in with the other kits. They will probably be able to tell me where i should start. I know i should also refresh on fractional math and decimal math, then go with the geometry/prealgebra stuff. Thanks alot for pointing this website out. It is really appreciated because good learning material is important.
It's on their FAQs page - they do blend in geometry throughout, although it really kicks off in Algebra 1.
From what you say, I'd recommend starting with the Math 76. If you have no problem with that book, then skip Math 87 and go to the legendary Algebra 1/2 book. If you do have trouble in 76, then do 87 before the Algebra 1/2 book.
If you start at that level, you'll have all of geometry covered.
