<p>@2blue,
Mark is retiring after this quarter, and a guy called Roland Greene is taking his place. I think SLE will continue to be more or less the same, as most of the section leaders and Suzanne Greenberg, long-time SLE coordinator, are staying. Definitely apply for SLE!!! Best of luck to your son. :)</p>
<p>@Crut,
Yes, you have to take one of the two as a freshman. IHUM is 5 units per quarter, while SLE is 9. You get a variety of different IHUMs to choose from according to your interests. Some are very philosophy-and-literature-based, while some are less so. There’s this more techie one called Humans and Machines and even one called Sex and Love in Modern Society. For SLE, you get a more well-rounded and rigorous liberal arts education. Also, SLE takes care of your PWR requirements, whereas with IHUM you still have to take one quarter of PWR (Writing and Rhetoric) for both freshman and sophomore years.</p>
