1 science professor, 1 research PI. I assumed the research PI would count as a "supervisor", and it's also a really good one as I've worked with him for 2 years now. I don't have any letters from work experience or anything like that, and I've also had trouble having the physician I shadowed write me a letter because he was busy.
It costs me around $60ish dollars to send my transcripts (2 community colleges + 1 university), and so I'm waiting for a response to see if my application will even be looked at, before I spend the money. Right now, I'm considering just accepting the cost and sending it all tomorrow but mostly I'm hoping I can get an email back soon letting me know. Do you think I should just send it, or wait?
