Mmm, I guess she is more street-smart than collage-educated... slightly superhuman, very nice to look at and not afraid to have a few sexcapades, yeah, i can buy that.
Based on her canon background she barely made it through high school, let alone college, and so yes her intellect isn't that great. Self-esteem issues probably contribute to the way she puts it about a bit, especially with people like Peter Parker climbing up walls and Flash Thompson showing off the new black suit all the time.
