As far as difficulty goes it’s a toss up. At my high school, dual enrollment classes were very easy. True they were harder than the regular classes, but their AP equivalents were just more rigorous. But I’m sure that’s a different story at some schools. I’d recommend the AP classes. They’re usually rigorous, and prepare students somewhat well for college. Plus the test is a nice sum up at the end of the year that can get you something good in college if you do well enough. I’d go with AP.
