They have changed freshman math so I am not sure my answer would still apply, but her is my D’s story. She was an incoming freshman last year and used all of her 22 AP credits. She did fine in all her classes including Calc 2 where she got an A. She is not a math wiz, but did do Tech prep right before first semester. Those who use their AP credit do fine if they do the work and look for help when they need it. Tech is a huge change from high school. Also, using your AP credit improves your time ticket when it comes to choosing classes.
