are you a freshman or sophomore? jw because your above plan might work for methodology classes, but this CERTAINLY will not work once you get to organic and your upper level bio classes.
I personally think it depends on the class. I attended my upper level advanced physiology class 4 times, the first day and the 3 test days and got an A in the class. My friend photocopied all her notes for me in return for some tutoring for the class. I did the same thing for Orgo II, because my prof was TERRIBLE, but notice that i said I didnt go to those classes but I still read and kept up with the course syllabus.
What im trying to say is that as you progress and become a junior/senior and encounter harder, more content rich classes, you "photographic" memory will only help you out so far. Personally I don't doubt that you don't have that kind of memory, but I highly doubt that youd be able to get an A in the neurobiology class I took prior to graduating, where each test was half multiple choice/half free response over roughly 7 DETAILED chapters per test, so just as a heads up, I would work on changing your study habbits. It will help you a lot down the road.
