<p>I don’t know why you think anyone here will know about some hypothetical odd situation. But I don’t think you really need the credit do you? Are you trying to graduate a semester early? My daughter just placed into Calc II, she didn’t try to actually get a credit. However in hindsight she should have started with Calc I. She did get a 5 on the AP exam, but her grades in Calc I weren’t the best and she had an extremely rocky time in Calc II. She did go on to a math-cs major though.</p>
