I agree that seeing the material more than a couple of times is necessary for most of us. I guess I was getting at the fact that going through the syllabus more than twice is different than seeing the information more than twice. I think I posted above how I study, but basically it's lecture, syllabus x2, and board prep/questions the rest of the time. Essentially my view is that getting big picture (and some detail) from board prep stuff puts you in a position to learn/memorize professor-specific-minutiae much more easily.
Using renal histology as an example, we were expected to know the epithelial types for each part of the nephron and while I had classmates making all kinds of tables, flash cards, etc all I did was learn basic idea of each part of the nephron and then take a look at the syllabus. So, if you know that the PCT is where most reabsorption occurs then you know it's cuboidal with tons of microvilli and basal infoldings. If you know that the descending limb is for water reabsorption then you know it must be simple squamous, etc. In other words, while some of my friends were splitting time between trying to memorize the details and actually learning the nephron, I just learned the nephron and the details fell into place; much less stressful. In fact, I'm pretty sure all my friends think I'm really dumb and near the bottom of our class because whenever they ask me questions about details 3+ days before an exam my answer is always "I don't know"... because I don't.
So it's all about your approach and how you choose to learn the material. Different strokes, but at the end of the day your goal should be to maximize efficiency. There's tons of time as an M1 to go through the syllabus 5+ times because really that's all you have to learn. Based one everything I've heard about M2 I'm pretty confident when I say that the 5+ times strategy isn't going to work if you also plan on doing step 1 prep during the year.
