We only have H/P/F, so not quite the same, but generally similar...
Here, pre-clinical grades only matter for AOA, and even that is weighted heavily towards clinical grades. Otherwise, there is no correlation that I've seen in our Match data that would say getting honors in pre-clinicals predicts matching into successful programs. For that matter, and it may be blasphemy on SDN to say this, but CLINICAL grades and Match success aren't altogether linked either. I've seen plenty of people ride the Pass train through pre and clinicals, and get into top-notch programs. Granted, some of them had 265 Step Is, so your results may vary.
