Testing Day 2

Well, today is my second day of testing. And I'm taking the Math section today. This is really getting me nervous. All of these thoughts are coming into mind- what if I don't get it done in time? What if I don't know how to solve the problems? All of the teachers give you tips for these situations, like to fill in the most reasonable answer. But I seriously overthink things at times and it worries me. I'm just hoping that I can do good on the test today, no matter what happens. Wish me luck guys!
