I just passed my TEAS V two weeks ago. I passed the first time. I watched many, many YouTube videos while taking notes. I also read through the ATI manual and did the practice questions at the end of each section. I had just over 3 weeks to prepare. I took a practice exam from the back of the book before I began and noticed I bombed Science, so focused most of my time on that subject. Marked the questions I had a hard time with and watched YouTube videos on those things. This includes some math and most of the Science. I am 28, so been out of school for a while. Definitely studied hard and it paid off. Good luck!
