Do they look at letter grades more than numbers as far as rescindence warnings go?
For example, which would one choose -- 5 B's all hovering near the A mark, or 2 B's hovering near a C? Suppose your average was 94. Second semester, your average is still 95, except now the standard deviation is much larger. Say 5 100's and 1 70 (a D-!). A concern?
I'm just planning for worst case scenarios. I think in two months I'll see this all as silly.

It's just a curiosity as well.
