What sort of resources does your family have in terms of supporting you through a gap year? Independent travel can be a little tricky when you’re underage, but there are more structured programs. Do you have any special interests? You could look into some non-credit programs in areas like arts, theater, filmmaking, et al, or possibly a computer-coding “boot camp.” You would not be a transfer student, technically, if you were not enrolled in a degree-awarding program. These options are only feasible for affluent families, though.
