Mometrix seems to be what everyone recommends (haven't used it myself). You can also find a lot of TEAS flashcards on quizlet. If you learn well with flashcards, consider Anki as well. Past that, Khan Academy likely has videos on many of the major A&P concepts. That said, is there a reason you're trying to take the TEAS before A&P? Its my understanding that most programs require at least 3 (if not all) science courses to be complete prior to applying. On top of that, there are several that will only accept your first TEAS score. Depending on how competitive the programs you're looking at are, and what your goals are, it might be worth reconsidering. Yes, that may put you "behind schedule" a year, but that's better than risking a poor TEAS score.
