Don’t be hard on yourself. This was a weird year (COVID) and colleges may end up being forgiving about grades, especially second semester. In any event, it is your junior year grades that most define your academic potential to colleges. You most certainly have a chance at “elite” schools. You can certainly work ahead this summer to make sure you do well junior year. You might even take an online course to show initiative, academic breadth or focus on a particular academic subject. It may also be wise to start prepping for standardized tests. You will be taking the pre-SAT as a junior and you might shoot for National Merit Scholar Qualification when you take that exam. A good SAT or ACT score may qualify you not merely for admission but also for merit scholarships at some schools (there are threads on these). You can always look for best college fit and consider ED1 and ED2 options as these may be a way to leverage even a borderline application into an elite admission. You still have some time to consider adding an extracurricular activity, perhaps something academic. Possibly talk to your high school guidance counselor. Good luck!
