What percentage of college freshmen repeat courses they had in high school?

<p>Fire, GenChem in college is much harder than the material that’s found on the AP Chem test. In fact, GenChem is often considered the first flunk-out class that gets many pre-med students to change their majors. My son took two semesters of GenChem (9 hours) at the local university via dual enrollment and 6 months later took the Chem AP test. He found the questions on the AP exam trivial compared to the ones he had to answer in his college exams.</p>
