Well, I got a BA degree in Econ from some university already. But now I am trying to take some open course to bring my GPA to a more respectable level (currently under 3

). So I went to the business department and asked if I want to improve my GPA whether I should take Graduate courses or undergrad courses? Well, she told me both are fine, all they look at is the last 90 units GPA. Mmmm....I dunno how accurate this is..because I always think u got one GPA for undergrad...another GPA for grads. If what she said is true, wouldn't that mess things up?
