<p>Brown allows students to obtain credit for Math 100 if they obtain a 4+ in AP Calc BC or a 5+ in IB Math HL.</p>
<p>However, theoretically, what would happen if someone were to get a 5 in AP Calc but, say, a 4 in IB Math? Would Brown still award credit?</p>
<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>
<p>The thing is, I’m planning on double concentrating, so I want to have the option of getting some pre-reqs out of the way if possible, to avoid overcrowding my schedule.</p>
<p>However, this question was mainly just asked out of curiosity 
I’m pretty confident in my math abilities, so this is more of a “what if” scenario.</p>
<p>I’m almost positive they’d still give you credit for the course, since you’re satisfying one of those requirements. If nothing else, you could take a placement exam to get out of it.</p>
<p>In that case, don’t worry about the credit, just the placement. Did you take this self graded placement exam?
