Correct. A lot of people, especially in H/P/F or P/F systems think that grades don't matter in the first two years and that "they will really study when boards come around." The first two years, in my view, are not primarily important for grades. They are important because 1.) they train your brain to assimilate massive amounts of detailed information, something you'll need to do for board prep, and 2.) they really get down the *concepts* of physiology and pathophysiology. Details may evaporate and can always be relearned during review, but if you are trying to understand something for the first time that others have been mulling over and integrating (perhaps not even consciously) for months or even years, you are going to be way behind.
