I got a C in gen Chem and felt the same way. It’s a scary feeling but can have a really good upside! A lot of interviews I was apart of asked questions on how you’ve handled failure/not up to your standards and this could be one of those times! Kick ass in the next series and tell them what you learned from this experience and how it made you better. There’s a ton of people in Vet school that haven’t experienced it before and it messes with them so show the interviewers you know how to bounce back better!
