Hi! I can totally relate to the feeling of being scared of standardized testing, I too had to retake the TEAS exam and got admitted with 84%. I bought the yellow ATI TEAS secrets study book from Amazon to study and further used that to guide my search for Youtube videos on each topic. In addition to that, I found watching videos of people who previously took the TEAS was helpful because they break down each section for you and it's easy to understand what you need know for each and possible questions that may appear on your exam. I also downloaded various TEAS apps (ATI TEAS pocket prep & ATI TEAS 6 practice test were a good ones) on my phone to receive free daily questions, obviously you can purchase an upgrade and get more questions but I felt that the free ones were sufficient for me. And lastly, since you have already taken the TEAS, you are familiar with the layout of it but if you want more practice, purchasing ATI's practice exam was really helpful for me in terms of getting over the anxiety of not knowing what to expect. Plus, I found that the scores I received on the practice exams were very close to what I got on the actual exam. It's a good indicator to see where you are and what you need to study. Hope this helps and good luck ! ?
