First suggestion would be to try and keep your mind at ease! I'm not big on standardized tests but I felt it was manageable, so don't worry, just study :) As far as studying goes, my best advice is to do lots of practice questions from lots of resources (apps, study books, quizlet, etc). Practice > reading material over and over. Only read and study topics you don't understand. The math is fairly basic so you should be fine. The reading section isn't hard, but it's tricky if that makes sense. Thoroughly read the question, and don't over think the answer. Also, on each question there is likely to be at least one silly answer to get rid of. For science, study up on your A&P. The questions varied greatly between hormones, anatomical structure, body fluids, cells, etc. Grammar section is tricky, but just study up and, again, do lots of practice problems!
