Your previous college experience as a dual enrollment student will help you in preparing for your first year. You have already experienced the rigor of college work, as well as different teaching approaches and access to course materials. Many of your college peers may also have previous college credit through a dual enrollment program, particularly if you stay in Georgia for college.
The courses you complete may be able to count toward your college degree. Each college or university has transfer credit policies that list what courses are accepted and how they will impact the courses you need to take for your major in college. If you are taking dual enrollment courses at the college where you plan to attend, you can reach out to an academic advisor or transfer admissions staff member to talk about how your credits will transfer.
If you are already accepted to a school, look at their transfer credit policies. You can google "School name Transfer Credit" and that will give you a start. You can also go to the individual school website to look for transfer credit information. It will usually be under the accepted student or prospective student information.
