<p>How challenging are the classes at jhu???
thx</p>
<p>They're exactly 7.2s on a scale of 1-10</p>
<p>They are theoretically filled with the "smartest" students throughout the world. Most are very motivated to succeed. That, coupled with the outstanding faculty make for some very intellectual courses. You have to be ready to work at Hopkins if you want to do well.</p>
