I'm in my third semester, will be graduating with my ADN in May :-)
Good luck, relax, and focus more on learning the concepts and less on the grade you get on each test. I know there is a lot of pressure about your test grades, but if you don't *understand* what your testing on, you won't progress through the program anyway. Be open to learning about yourself, your previously held ideas, and new ways to see the world. Find your people, seriously, find people to laugh/cry/share this experience with, they are there I promise!
Pace yourself, it is a marathon, not a sprint! Be kind to others and yourself!!
