Hi there! I just took my TEAS this morning and I got a 83.3%. That is better than 93% of the nation's scores! I used as many online practice questions as I could find, as well as the ATI Study Guide and YouTube videos. I studied like crazy! I still only got a 62.5% on the Science portion, but the national average is only 53.6%. My advice - study, study, study your Science facts. The ATI Study Guide is pretty good and covers everything you'll need. I studied for about 3 weeks total. Any more would have been overload I think. Good luck!!
