I graduated in 2019 and have worked for the past year in Finance. I was able to get a letter from my current work manager. I understand having an academic letter is important. Over the past month, I have emailed ~10 professors whose classes I have done well in, as well as a few career and pre-law advisors. I have only received 1 response and they said they were too busy and now was not a good time. What should I do? I was hoping to apply before Thanksgiving, but that is looking less likely. I can get another letter from a previous internship supervisor, but that would leave me with 0 academic letters. Should I apply with 2 professional letters and apply earlier, or delay applying and hold out (hopefully) for an academic letter?
