Oh yes, the joys of information overload!!! I myself am also a very visual learner... when I took A&P 1, I had to teach myself to study in a whole new way! I know you have a lot of information to study in a short amount of time, but DO NOT try to cram it all in, and try not to approach it with the thought "I have to memorize it all." This will only put undue stress on you, and in the end you won't end up absorbing anything. What helped me was to begin by reading through the gobs of information as if it were a book (and forcing myself to find interest in the 'blah' subjects lol.) After completely (and calmly) reading through, I'd break the information down into groups and rehearse the material as if I were teaching it to someone myself. It sounds dumb but it was like I was role-playing as a professor in my head lol. And yes, if you try to write out flashcards for all the material you'll be left with no time to study them. Instead, try making a list when going through the information on terms and concept that are are big struggle and then make flashcards from there. I know that all this information may be something that you may already know and may be completely useless, all I can say is... hang in there
Fortunately, I found A&P 2 to be A LOT easier, many of the main concepts that were difficult in A&P 1 were reinforced (actually, most of the information in A&P 2 was reinforced!) Good luck to you!!!
