either contact Georgia colleges or take a gap year and reapply again next year. I suggest the best alternative would be # 2. Do NOT enroll in college courses, because that will immediatiely disallow you to apply as a Freshman, and greatly reduce your chances of acceptance.
If you decide on the second option, then ask your HS teachers and guidance counselor right NOW for fresh letters of recommendation that can quickly be sent to new colleges in another couple of months.
Once you are out of HS, next years Seniors will be their priority for LORs. So ask for them now.
