My 20-year-old cousin has been taking classes at her local community college for two years, and she's still nowhere near the required units she needs to transfer to a four-year university to pursue her degree in psychology.
Why? The classes she needs are filled to capacity.
My advice to her was to start looking into online courses for credit.
Bill Gates himself said it: “It’s very clear that five years from now, on the web, for free…you will be able to find the greatest lectures in the world on the web.”
