<p>We had lots of free time. The only class of those three that actually took a serious amount of time was Chem 4A, and not because it was hard, but because of the tedious labs. My lab was on Thursday, and I spent about 8 hours each Wednesday night writing the lab reports. Chem also had a problem set due each Monday that took about an hour. Aside from that though, math and physics for the entire week took three hours or less each (physics labs are completed in the lab itself, not after). I completely finished my math and physics on Saturday each week, and the chem problem set on Sunday. I didn’t have ANY work during the week, aside from the lab and preparing for the exams (which weren’t that hard).</p>
