AP courses are more demanding than other college preparatory courses taught in high school. They move rapidly and cover a great deal of material. If you are a strong student in a particular subject area, then you will probably do well. Your current teacher can advise you.
Since AP courses are more demanding than other college-prep courses, AP students receive 10 points added to their average (in each AP course) at the end of each semester to balance any grade discrepancy. (Note: The 10 points is not used in calculating GPA for Hope Scholarship eligibility. See your counselor for details on how your GPA is calculated for Hope.) Students who excel may have higher than a 100 average in the class.
Colleges look favorably on students who succeed in AP courses. The presence of AP courses in a student's transcript indicates that a student took the most rigorous courses available.
