It seems very unlikely that courses at a CC are generally equivalent to those at Cornell. If so, that would be very odd because their missions are so different. The CC usually cater to students who are often not college ready and who choose community college because they are ill equipped to go to a 4 year school. Obviously not all but many. If in 2 years those schools can take students who are in need of remediation and give them the sort of rigor Cornell promises, then that’s amazing. The people I know who went to CC were certainly less academically strong then those who went to Ivy League schools yet they got A’s fairly easily. And the few I knew who went from CC to universities, not Ivy League, struggled and went from A’s in CC to much lower grades. But I’ve not known anyone really well who did this in a while so things may have changed. But either the rigor of the CC or the rigor of the competitive school has to have changed for them to now be similar.
