Diva,
Just relax because you know you can do this. You just did it and you were totally fine so you will be totally fine tomorrow. What is the worse that could happen anyway? Even if you bombed the exam, which you will not because you have studied plenty, you will survive and it's not the end of the world right? Just believe in yourself that you can do this, you have done this, and you will continue to be able to do so in the future. You are in control, the anxiety isn't, so take over, do some deep breathing, relax, and hope for the best. You will be fine and deep down you know it. Buenos suerte!
