Hi -If you studied the TEAS book and other books/online (general biology, chemistry, etc.) and took practice tests you should be fine. The test has a lot of tough chemistry - especially know mitosis and meiosis, scientific method and critical thinking, some common and general chemistry equations/formulas/definitions/names). I used the ATI/TEAS book, purchased the on-line ATI practice exams (both A and B) and reviewed youtube videos on pertinent science/chemistry topics. Take deep breaths before starting the test, watch the time and make sure you answer all the questions!! If you skip questions, allow enough time to go back to these before your test finishes for that section. Reading is first, followed by Math, Science and the last subject tested is English Grammar
. Once your allotted time is done for one section - you proceed to the next section. I found all the sections (except Chemistry/Science) to be very similar to the ATI study manual and practice tests. The Science/Chemistry section is hard - topics are covered in the manual, however the questions on the actual test more detailed!! So, use your critical thinking skills to determine the right answer. Good luck!
