I'm not the best test taker, but did well on it. Practice the ATI TEAS book and memorize the conversion table (you can get it at the ATI testing website or amazon
). The test questions in the book are very similar. Most schools who use TEAS pay more attention to reading and math scores. Science is some odd subjects has geology (seriously why would I need to know about rocks as a nurse), but I think they are just testing you if you can read a graph. Some of these schools also weigh in GPA, if your pre-req are completed, and experience.
I agree with the previous poster, don't let the schools' entrance exam scare you off. TBH, I found the schools that did not require entrance exams were harder to get into. I was put on UIC waiting list, and by the time I got the acceptance letter, I was ready starting orientation in another school (that I tested in).
