I took my Teas 6 exam 2 days ago, and only had a little over a week and a half to study for it. I bought the study book off the ATI website, along with the practice exam A. I scored a 71.9 on the practice test, and then scored an 81.2 on my actual teas test. My best recommendation to you is to make sure that you know the science portion, because it contains the most amount of questions on the overall test. Math is pretty basic, and the reading and english wasn't bad either! Best of luck to you!!
