CCs don't teach Junior or Senior (300 or 400 lv) courses. If you stay at one longer than two years it is because you are going part-time or started with college-prep courses.

I spent 3 years (including Summers) at a CC then transferred into a top 10 engineering program. The 'extra' time was required because I needed to take a year of math classes before calculus.

And IMO, the CC's pre-engineering program left me better prepared for the university's department/major coursework than some of my peers who started at the university.
