I think I flopped my pharmacy interview

I think I flopped my pharmacy interview I just finished an pharmacy interview at an uni I wanted to attend to. I was able to answer most of the questions but I stuttered quite a bit on some of the questions and some of the questions were so confusing that I gave short simple answers to them. I’m honestly happy I addressed it before the interview but I’m so angry at myself for working so hard and revising the questions to throw away all my hard work to stuttering on most sentences.
