Well, Micky_mouse, first of all it is not called 'junk courses'. They are called lower level courses or prerequiste classes before you can take 3000 and 4000 classes in university. I understood, thats all it matters.

Well ur community college is a 2-year college, so all it does is - offers a 1000 and 2000 level classes. And it depends on 2 things how many credit classes you can take in a community college, before you transfer to a 4-year college. Ur Major and The university u transfer.

The best thing would be to decide ur major and choose 4-year college and talk to advisor and do equivalebcy check. Usually, u can transfer from anywhere 45-60 credit hours depending on major and college. In some cases i Have ssen upto 64 crdit hours.
