It depends on the school and the student's ability.Those who had high school math in middle school will typically have geometry. Those who didn't have Algebra 1 in middle school will have alg1. If the student needs a different math, there are usually general math classes. Also, depending on the school, the student might be in the integrated series (mixes geometry and algebra over three years) instead of traditional Geometry and Algebra classes. I personally dislike the integrated math (I've had both thanks to school transfers).So, there are many factors; I'd suggest you find a copy of your local high school's program of studies (it has all available courses in it and recommended courses).
