In determining admissions, colleges do not prefer dual enrollment over AP classes or vice versa. Rather, the admissions officers will look at course rigor. Why? Because not all schools offer dual enrollment or AP courses. Generally speaking, colleges will look at the rigor of the courses you have taken, the grades you received, and how you compare to the pool of applicants.
What Is the Difference Between Dual Enrollment and AP Classes?
Dual enrollment classes are college level courses that are taken in your high school and are on your official high school transcript. You pay for the college credits through your high school. Whether those college credits will be accepted or not will depend on the dual enrollment requirements of the college that you attend, such as the grade you received, the type of course, etc.
AP courses are Advanced Placement courses that are given through the College Board. Typically, in order to get college credit for AP courses, you need to achieve at least a 4 or 5 on the AP test, depending upon the school, and for some colleges and certain AP courses, a 3 may provide you college credit for the institution you eventually attend.
