<p>[Mathematics</a> 230a](<a href=“http://classes.yale.edu/04-05/math230a/]Mathematics”>http://classes.yale.edu/04-05/math230a/). That’s the course page from 04-05. </p>
<p>I think the BC requirement is just the “on paper” requirement. I’d assume that the two main things you would need to know are knowledge of proofs and mathematical maturity. Spivak’s Calculus can help you develop both. </p>
<p>To prepare for the course, I would definitely know Spivak well, and also Linear Algebra Done Right by Axler. For the vector calc portion, I guess know div/grad/curl like the back of your hand eh?</p>
