Current undergraduate here. At the risk of repeating stuff others have said above, here’s a summary of the Core:
Non-negotiable requirements
3 quarters of SOSC. Your kid is taking this - no getting out of it. Lots of reading - I had 40-60 pages of dense reading per class. Less reading if your kid takes Mind. More if he/she/they take(s) a stab at Classics. I recommend the latter, but YMMV.
2 quarters of HUM. Again, everyone takes this. It guarantees that every second-year, even the STEM/Econ majors, can string a few sentences together. No placing out of it.
1 quarter of art. Lots of fun courses to choose from, but the College doesn’t offer enough sections, so getting into art core classes is tough. Your kid should get it out of the way ASAP. There are invariably 4th-years who need to get into the right Core classes to graduate. It’s not fun. Don’t be one.
2 quarters of CIV. A history course by another name. It’s here so the STEM/Econ majors know the pyramids weren’t used to store grain.
Some wiggle room
Biological sciences. You can place out of Core Bio, but there’s no escaping the topics courses. They’re here so the humanities/social science majors know vaccines don’t cause autism, antibiotics don’t cure colds, and chicken doesn’t grow on trees. From what I’ve heard, these can be fascinating or a snooze - depending on the class (to an extent) and mostly the professor. Lots of topics to choose from.
1 quarter of HUM/CIV/art. You need a total of 6 quarters in these categories, so Sam-I-Kid should take an extra quarter of whichever one seems most appealing. I personally opted to go beyond the required 6, because I enjoyed the courses I took. YMMV.
YMMV
Math. Almost all students take some math classes - a quarter of the class majors in Economics, and UChicago’s approach is math-heavy. Those of us who prefer the humanities and social sciences still need to make change and solve Delta Epsilon proofs once in a while (one of the two, anyway). Several AP courses, with a good score, will provide credit for Calc 151. AP statistics can provide your second math Core credit. A mix of these may provide some credit, or none, depending on courses and scores. The placement test is easy; the accreditation exam is harder. If your kid wants to place into the 160s sequence, that’ll require a good score. It’ll also mean a lot of work - I have friends who’ve spent many long nights on one prof’s Problem Sets from the Black Lagoon (they still recommend the class and professor). Expect lots of proofs.
Physical sciences. AP chemistry and any Physics C course will let your kid place out - if Sam-I-Kid scores a 5. A pair of Physics C courses will do the same.
Foreign language. Congratulations! Your kid has fulfilled the foreign language requirement as a 0th-year. Take more classes in that language and aim for fluency. Or pick up a new language. Or don’t. It’s up to Sam-I-Kid.
Courseload, rigor, and credits - general thoughts
At the very least, the core will involve 10 courses. With no AP credit or language competency, or a voluntary choice to take some classes anyway, this rises to 18.
The English major requires 13 classes (11 if we ignore the 2-quarter language requirement). The longest possible STEM majors are Molecular Engineering (and Biochem or a BA in Neuroscience, apparently). All clock in at 19. At most, your kid will be required to take 47 courses (all the above except the language requirement). During 4 years (12 quarters) at the college, a student can take up to 48.* If a Core requirement is going to be almost entirely review/not that interesting, placing out is good and frees up space for your kid to take some electives. If it’s a key area for a STEM major that your kid feels uneasy about, take the class - the professors here are excellent, and upper-level classes can be difficult without a proper grounding in the basics. It’s Sam-I-Kid’s choice (with helpful advice from Sam-I-Parents, no doubt).
*Yes, students can take 5 classes per quarter. No, this isn’t a good idea.
If a hefty reading load is an issue, consider taking SOSC as a second-year. I had to rely on Sparknotes a few times when I took both as a first-year.
On honors vs. regular: There’s no “honors track” except the thesis (in place of a Long Paper), which is required to be considered for honors in many humanities/social science subjects. The benefit of honors is learning more/tougher material and pushing yourself. Be aware that in honors classes, students should plan on hefty workloads even by UChicago standards. This isn’t high school, so taking Honors Everything isn’t expected - or recommended.
Last but not least, my advice for Sam-I-kid: have some fun! The work is tough, and it’s easier if you aren’t holed up in your room all the time. Take a break. Do stuff that makes you happy with housemates and friends. Be good.
