Can you post a link to the textbook?  Without seeing the contents, I have no idea which courses to recommend.

If you are preparing for university, you may want to try the AP courses (Calculus AB, Calculus BC, and Statistics).  If you are doing a Foundations or Math for Everyday Life course, you want to try a combination of Algebra and Geometry.  For Foundation, you may want to try Algebra I and Algebra II, Trigonometry, and Precalculus.  You may not need to complete these courses for Math for Everyday LIfe, but you should try the first units in both Algebra and Geometry.
