    "Honors courses add 0.5 and AP, IB and college (dual enrollment) courses add 1.0, as in the North Carolina State Board of Education policy; an F earns 0 in any course. Schools differ, so check your school’s scale.",
    "Courses marked Not counted (pass, withdrawal, incomplete) are left out. Credits are from 0.01 to 30 per course.",
    "Both GPAs are exact before they are shown to two decimal places, rounded half up. Some schools cut off (truncate) instead."
