@JBStillFlying Virtually all undergrad classes except for the Core are 2000-level - the only exceptions I think are the new Signature classes. There are a ton of introductory 2000-level classes because of that - for example, the introductory PLSC classes, which are explicitly geared towards students brand new to the subject. Intro to Political Philosophy is similar, I’ve actually personally taken it.
The preselected courses are not rigorous. That’s the problem. There’s no way those courses are too rigorous to take more than one per quarter - I took three at once plus a 4000-level class my second year with no problems. They’re run of the mill classes, many of them introductory and no harder than the average Hum, like the ones I listed above. The pre-approval requirement is also not unique or a mark of rigor, not sure why you think it is - PLSC axed pre-approval a couple of years ago in an attempt to increase the rigor of its major, as their pre-approval list was letting too many students take too many classes outside the department. It’s now case-by-case.
Regardless of whether it is rigorous in some absolute sense, it definitely has absolutely no reputation for rigor, which was my original correction before we went down this rabbit hole. Pre-law students are not the best gauge for a reputation for rigor given that rigor is anathema to them, and the pre-law frat is made up of the most pre-professional of the pre-laws. For better or for worse, nobody takes LLSO seriously. The university nearly eliminating it did not help its reputation. If anyone is curious to get a third take, the most recent Reddit post on it also mentions its utility for GPA-maximizing.
Fundamentals is brutal FWIW, not for the faint of heart. It’s living proof that it’s possible to do an interdisciplinary, very open major in an intensive and rigorous way.
