<p>I’m not sure I understand your question. If students have mastered the lower division material because of advanced coursework when they were in high school, could they not move onto the more advanced subjects in college? Are you asking why don’t more schools offer honors versions of introductory math courses for math majors who are well prepared for them or are you suggesting that the “honors” courses at these particular colleges are more rigorous than another school’s “honors” course (in which case, how would you even know that, unless you’ve taken these courses)?</p>
