I am in high school and my school offers very little in the way of higher level STEM classes. I want very badly to delve deeper into this topics so I want to take college classes over the summer. I want to take a Computer Science class and if possible I want to take an Enginnering or Science class. Since they will all be introductory and I am a (not to brag) bright student, how many classes do you think I could get away with and still get As? Also, what specific course will fit my areas of interest? (software, engineering, medicine, business/economics). I live in Florida if it makes any difference.
