I'm a little confused what you're doing with school.
You're a senior in high school, and you're going to go for your BoS in Computer Sciences, so your plan is to stay in high school for another year, and then go to college, and then university? Why aren't you going to just graduate with everyone else, with this being your final year of high school, and go to community college for two years to save money (since community college is a lot less expensive in their classes and credit hours) and in the process, improve your grades to earn a chance at getting a scholarship for the university of your choice after two years is up and you get your associates degree?
