I won’t say five AP classes are too many. Many students take five or more and do well. What bothers me is the lack of focus and oddly, rigor in your choice of classes. You say you may be interested in engineering but I don’t see AP Chem or a fourth year of math. I’m will aware that you are two or three years ahead in math and maybe that explains the lack of math in senior year. But if you are that strong in math, it would be a pity to just stop math for a full year (you go through math withdrawal).
.If you had expressed interest in the areas of environmental science or psychology among all your interests, they would make more sense. I would drop these. I would really think hard about which classes you enjoy and move further and challenge yourself in those subjects. Right now, your senior schedule looks like an attempt to appear rigorous with the number of AP classes but the choices don’t really mesh with what your areas of interests, as broad and varied as they are. I get you want to explore areas, but maybe you don’t need to do that with AP classes?
Last, I noticed that all your reaches are out of state and all your targets/safeties but GT are in state/ DC metro area. Again, put a lot of thought into what you want: size, location, presence of campus, urban vs rural vs suburb, type of student, and so on. I feel there’s a certain amount of “default thinking” here. Do you want to go to GMU or GW if that turns out to be your only option? If not, replace the school with one you do want to attend. Have you visited schools yet?
