I reviewed the ATI material and watched supplemental videos on Khan Academy and Crash Course. I have not had a science in quite some time- and I did just fine! It was difficult from the perspective of someone who hasn't had A&P, NUTR, or CHEM in a few years (if ever). However, it is totally manageable (I scored advanced). You will do great! Good luck! I am a little nervous because of past mistakes I made eight years ago that REALLY lowered my college GPA (like not ever going to class-or dropping). I FINALLY, after 4 semesters of straight A's, have brought my GPA up to a 3.0 from a one point something (sad- I know). I think the cut off the last few semesters has been 3.1!
