that's why schools look at the institution you took your classes at.
if u took it at mostly CCs (not that its anythng wrong) and u have a 3.6, a person w/ a 3.5 at a UC will be looked at much more favorably.
its no coincidence that ppl have higher GPAs at CCs.
my GPA drops at UCSD but 4.0 at CCs for 8 classes that i took.
