edit- found it. 3 intervals for first 2 years, 4 intervals for last 2 years of med school.
and pbl...
I'm not sure what exactly you're referring to above.
During the first two years, the grading is H/P/F, and in my few years of experience around here, and watching a few match days go by, MD/PhD's needn't bother with the H's (same for med students, for that matter - though there is invariably more chatter about things like that amongst classmates whose clinical careers are more proximal than ours) during the pre-clinical years.
In the clinical years, grading is H/P/F as well, with some clerkships offering a HP in the mix as well, I believe. Despite the PhD years gap and how they may have done in the first two years, MD/PhD's nearly uniformly do excellently during those years. People generally don't worry about getting into residencies of their choice.
Transcripts do not show rank, nor are there any breakdowns of grades by sub-scores (i.e. PBL). Things like PBL grades are factored in with quiz grades and other things that I can't remember to produce one final letter (H/P/F). Clinical grades are a weighted mix of performance and shelf grades, which varies from clerkship to clerkship (but is cleraly explained at the outset).
In general, there are ways to distinguish oneself through grades, but it seems to me that there are far better uses of ones time.
