Cumulative GPA and dual enrollment classes

[MJA87]

I just looked at my undergrad transcript for the first time in a while and had a couple questions:

 

My cumulative GPA from my undergraduate institution was 3.41, however my GPA factoring in 24 credit hours from dual enrollment (taking college courses while in high school) classes was only 3.30. I'm wondering what GPA grad schools will consider, and if it's the lower of the two, is there any action I can take to explain the lower GPA?

 

Additionally, some MPP programs require a B or better in a microeconomics class and/or a stats class. I got a B in a stats class in 2006 (as a part of the dual enrollment) and B- in a political science research methods class (basically a stats class) during undergrad, but I don't know if grad schools will care that I took the stats class so long ago (8 years) or that the more recent stats class is a B- rather than a B.

 

It's frustrating looking at my transcripts for the first time in a while and realizing I'm not as strong of an applicant as I thought I was. I'm beginning to doubt my competitiveness for some of the programs I plan on applying for 

 

Any thoughts or advice are very much appreciated.
