<p>I’m back again today. </p>
<p>For Warrior2005, the undergraduate courses are usually big (100 to 200 students), the upper division courses are much smaller around 30 students.
Every math majors take the same sequence of calculus to differential equation (in UCLA, the sequence is 31ab,32ab,33ab).</p>
<p>For TheIcon, thanks for your compliment.</p>
