i took the teas on Feb 28th and studied my butt off only to end up failing the math and science. I took the online assesment and scored like a 90% on it, so i was confident i would do ok on the actual exam..NOT. The math and science was so far off base from what ATI has you study for. I have to pass each subtest w/ a 60% and an overall composite score of 60%, so needless to say I will be taking it again on March 28th and this time i have ordered the Kaplan book.. I will let everyone know how that works out for me:) From what i've seen on the post here, many swear by it.
