GRE Score/Applying for MPP

[DonewiththeGRE]

I just took the GRE and my estimated score was a 161 V 157 Q

I have a 3.25 GPA with a philosophy major and Germany minor at Washington and Lee University, and I am hoping to get that above a 3.3 by the time I graduate next year (I'll be studying abroad for a semester, so I'll only have one semester to get my grades up).

If I work for a year or two in policy after I graduate, will that, combined with good letters of recommendation, balance out my mediocre GPA?

I'm looking to apply to MPP programs at: USC, UT at Austin, Georgetown, Cornell, UVA, and maybe also Stanford and Columbia.

What do you all think?

Thank you!!
