Does your school offer AP Calc BC to kids on a more advanced math track? Does it offer AP Precalc before senior year to some kids?
To make yourself more competitive, I suggest showing your passion in service/community-oriented ECs rather than a second foreign language. GT values service in its holistic admissions. Use the extra spot in your schedule to try to increase academic rigor, in math and science preferably. This should be a discussion with your school GC now to understand your options for junior/senior year schedules.
CS is now an impacted major at GT so it is a more difficult admit than ever. It will be very important to show you are one of the top students in your high school and you’ve taken the most rigorous classes your high school offers. You may get a slight boost as a female since GT tries admit a gender balanced class.
