I could be very wrong about this, but I don't believe college courses are weighted in my state. At least, at the meeting I was at where I heard about all this stuff (and listened with only one ear because my DSs were only 3 & 6!), grades were a concern and no one reassured parents with this bit of info.

I realize this isn't much help, but grades and weighting would certainly be something to check on.
