<p>Does anyone know how hard this one is? I got a 5 on the AP exam but I still have to take it because I didn't take the E&M part.</p>
<p>The test is reasonable, just study well for it: <a href="http://web.mit.edu/8.01/www/%5B/url%5D">http://web.mit.edu/8.01/www/</a></p>
<p>I was an idiot and didn't prepare well, hence I failed.</p>
