I know a lot of family friend’s kids that were smart, motivated in high school (high GPA and all), went to community college to “save”. Four years after, they’re still in community college. What happened? Not sure, but the environment in a CC is not conducive to some kids and that they are being pulled down and “derailed”. But of course, every kids are different.
Also most classes in CC are not competitive. My high school daughter took a mid-level math class this summer after her freshmen year and they were being spoon fed, more so than her Honors class in her high school.
