Hello, I've recently applied for 2 Medical Physics graduate schools (MS). Shortly thereafter I realized a few minor problems with my application. I've noticed 2 one-letter typos in my essay, both were caused by changing the noun from singular to plural and not removing the -s after the verbs. Should I be worried much about this? And, I noticed that on my resume, I forgot to put in the list of major-related softwares I have experienced. (Matlab, Stella 9, CrystalBall). Do you think not having this information on the resume will impact negatively? Thank you.
