Hi, CLEP newbie here. My daughter is a HS Senior. She is a very good student, taking five AP classes this year and is going to be a freshman at UNC-Chapel Hill. She was in a car accident and has been in pain, going to PT 3x week, on pain meds to sleep, had to quit work, quit coaching soccer. It really messed up her studying for the AP exams, especially Chemistry and she's afraid she didn't do well enough. She is dissapointed...she needed to get a 3 in Chemistry to get credit for a science class at UNC. She's taken two years of HS Chemistry and is also taking AP CalcAB, which she is doing well in. She wants to take the CLEP Chemistry exam this summer if she didn't get a 3 or better on the AP Chem. The question: Are AP and CLEP tests generally comparable? Harder? Easier? I guess she should go get a CLEP Chem book.... Can you take CLEP at any time or is there a registration period? Grades aren't ready on AP until July. She only has a short window between when AP scores are available and when she leaves for school in August. Thanks in advance everyone!
