Hey! I am preparing for the TEAS V as well and hoping to sit for the exam in a 2 weeks. For math, I did the practice tests in the ati manual first. This helped me narrow which areas I needed to work mostly on. I went through the math review section afterwords and as I was reading through, I was able to distinguish the parts that explained the mistakes that I made on the practice test. McGraw-Hill also has a great 5 TEAS test book that is worth looking into. Good luck on your TEAS !
