Well, you never know where your life is going to take you @sunssi. When you have a well-rounded education you have a lot more control over that. When I graduated from HS I didn’t even think of becoming a teacher….but when all was said and done I was awarded my education degree when I was 31, thinking to start teaching at the elementary level and work my way up. Had dreams of teaching college lit. However, as it turns out, I now teach adults in a high school diploma completion program. It’s not a GED program. The actually take the classes they missed, so I have to know everything I learned in High School. If I’d had the choice of opting out of something, I’d be at a serious disadvantage.
Besides, even if you don’t consciously remember something, it doesn’t mean that you don’t use it unconsciously in different ways through out your life.
As to what your said about self-teaching subjects that you enjoy…absolutely! I can pass a HS science or history class without even looking the chapter over! I can easily explain things to the students in those subjects. I do have a harder time in English and Math, but I’m getting it, slowly but surely.
