Oh, I see.

So is this class a semester class? When I was in high school we had seven classes/day that were all year long but my son's school only had four classes/day and they were half year classes. Is dropping out to repeat an option? Or dropping out to take a different science?

What do you want to major in when in college? It may be different now but when I was in college we had to take core A, B and C classes, and science/math was one of the cores.
