I highly doubt that it will be an issue -- these classes at my school (read: GenChem and Physics) stick out on my transcript as the only 4 credit hr courses among a sea of 3hr's+1hr labs. I think adcomm's will crack the code.
Yeah haha. The engineering physics lab sequence at my school is 2 classes, 2 units each, graded. And apparently it's impossible to get an A. Sucks for them. 😛
