<p>Are the problem sets for Ochem (chem 140a) over the summer mandatory to attend? Also are they weekly or just one day for the whole session?</p>
<p>They aren’t mandatory. I didn’t go to any when I took Summer Session I with O Connor. Are you taking 140A for Summer Session II?</p>
<p>Yeah I’m taking it Session 2 with Albizati</p>
<p>Albizati is honestly a joke for 140A. He gives like 30% A’s so take advantage of that.</p>
