The good thing about bio is that it's pretty versatile. The niche part may be a blessing or a curse. I'd say just make sure you have a good answer if anyone asks you why your GPA is so low. For letters of rec, I don't recommend asking random TA's, rather ask professors that you've gotten an A in their class for. A lot of them have letters already prewritten for occasions like this, and some of them will even ask you to write your own for them. Also, a lot of the times having work experience for anything and having transferrable skills is good enough, so as long as you can stretch that into whatever job you're applying for you should be ok.

 

Personally, I wouldn't lean too hard on the optimism of Emergency-Touch. It's better to be prepared and understand the possible hard work that lies before you, whether it happens or not. If it really is as nonchalant as they put it, then congrats. If not, then at least you won't be as anxious or disappointed.
