Most high schools offer such courses.
However, very few students take them. They have lost interest in math somewhere in the 6th to 9th grade. It is important that the students see some uses of mathematics in other than physical applications and statistics, which is hard to teach except in a routine way, could be good for this. By the 9th grade very few students care for a math education. There is a lot of confusion about how to teach math in junior high and a lot of kids drop out.
