Why is it out of your reach? Because they are too expensive?

If you want to study at a better college, look for professors in your field, find someone that does something interesting, and ask them if they will take you as a student. If you are good, some institutions will actually pay you for studying there.

This is easiest if you already have at least a bachelors degree, and want to go to grad school. At least in Europe, most grad schools pay PhD students (in science/engineering), and if you are smart, it's not that hard to get accepted.
