You can talk to me, I am almost done with college. What do you struggle with in high school? And what is easy for you?
What college and career do you think you will choose? A lot of people change their career goals in college, and they waste time and $ because the courses they took are no longer relevant to the degree they are trying to earn. So I suggest you gather information about the careers you're considering, and talk to college seniors about what the process of getting a degree in that field is really like.
