Math 155a Professor

<p>I heard that math 155a is a really hard class and I'm hoping any current student could shed some light on who the better professors are since a couple of the professors have taught classes before but do not have ratings on rate my professor. The professors are Gil-Ferez, Koca, Antolin-Pichel, and Klaus.
Thanks!</p>

<p>just don’t take koca, he was my ta 2 years ago and sucked</p>
