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

<p>Our S was able to use his 60 credits to get his advisor to waive his engineering chemistry course requirement. He didn’t take AP chemistry, but I think the advisor was impressed by the sheer # of AP & college credits S entered with. It did help him satisfy a few general ed requirements, but we were glad he re-took all the math & physics because he missed a lot 25-50% of his class days in HS due to illness. Taking it again in college gave him a more solid base to move forward with and provided him with a nice cushion to have a great GPA in his field.</p>
