<p>Biology: Great question. You get three chances to apply and get in as a freshman–call the school and see if this applies even if you have some college credit. Say something like “I’ve taken a few college courses, but dropped out because of compelling circumstances”, and see what the response is. Even if they say no, it looks like there are a couple of safety nets.</p>
<p>(i) Apply as a transfer. It’s a lot harder, but you get a second crack at the process about one and one half years down the line. Make sure you go gangbusters and kick a-- in your coursework, though.</p>
<p>(ii) Try the Eli Whitney Students Program (google it). It might be a bit of a stretch considering you’re probably not too much older than the “conventional” undergraduate, but if you tell the people looking at the application that you’ve had exceptional circumstances (no offense, but if you say “offset by lack of intellectual stimulation or company at my old school”, that probably won’t work). </p>
<p>Do your due diligence. Scour through the yale college website and do google searches for things that can act as kickers or exceptions to the normal application process for non-traditional applicants. Look for things people have tried before to get into Yale “through the back door.”</p>
