Your grades sound good, so is this more of a test anxiety issue? Don't give up, but I will say it would be wise to find some coping mechanisms/ test strategies prior to nursing school, because OH BOY are there a lot of tests in nursing school. Even when you graduate and get a job, there will still be required annual education (probably online quizzes). I would say take a TEAS prep course or buy a TEAS prep book (you could get an old or used one or rent one for cheaper from a place like Amazon or CHegg probably) I liked to chew gum while I studied and listen to calm music, so then I associate things I like with test taking. You could also take a "practice test" and have a friend pretend to be your proctor and see how you do. Just have confidence in that you know what you know and you are SMART, and know how to eliminate/ narrow down questions. Hope this helps! Good luck ??
