As mentioned before it can come down to the kid and how much rigor he wants. My D as a perspective Neuroscience major plans to enroll in the Integrated Science Curriculum at Princeton. It’s 2 courses each semester Freshman year that covers intro CompSci, Physics, Chemistry and Biology which would be 6 courses if taken separately. ISC has a heavy math component. It’s notoriously rigorous with 15-20 hours a week of Psets outside of class. Supposedly about half the students drop down to the regular classes after 2 weeks. In 2021 they’ll be students graduating with a Neuroscience Concentration and some will have done the ISC and some will not. They’ll both have the same degree but some students will take a more rigorous route to it. Princeton has a number of these types of things like the Humanities Sequence, etc.
