Help! I am not understanding A&P. I felt confident about the first lecture over chapter 1 (just an overview of A&P) and part of chapter 2 (chemistry). But today he just dumped so much material I do not understandddd. Part of it was over the last half of the chemistry and we started on chapter 3 (cytology). A lot of the students in there seem to be getting it and have probably taken chem within the last couple of years or are fresh out of high school. We have only one more lecture before the first exam because of labor day. So next lecture we are going to continue lecture on chapter 3 and then start with chapter 4 (histology) and chapter 18 (cellular respiration). I record lectures in class and it has helped so far. But right now I am really not grasping half of this chem and the chapters over cells. Help! I really do not want to fail. Are there sites or books or any other tools that will help? I'm going to ask some friends too but I know many of them are busy with school as well. Are all of the systems going to be this difficult or will it only get tougher? Exam 2 will be over the integumentary, musculoskeletal, and cardiovascular systems.
