You sound like a high achiever. There is only so much that you can do. But as Jason said,any experience that you can get on that resume is going to help you out.
Now don’t turn your nose up thinking that I am athletic and toned…..many pounds from it. Have you considered meditation, yoga, Zumba, or just brisk walks? I will be honest with you, I have an ADN and BSN. My Senior year of the BSN, I chose hypnosis prior to exams, on the morning of the exams.
I did not want to be made to walk like a chicken or anything (lol), so I chose a personal friend who is a family counselor and my PCP’s wife. I was calm before the exams, but had just enough anxiety to keep me sharp.
