Formal post baccs don't really do anything for you, though, unless you have a weak academic background (i.e., poor GPA). The linkages usually aren't that great (not to mention the fact that only the top X% will be offered the linkage anyway and by this point everyone is a "top student") and you're paying a pretty penny for them anyway. I'd go cheap. Find a small public 4-yr and go there. Take the courses and get on your way.
