MPP 2011 applicants

[jsmj21]

I had applied in MPP program in GSPP last year. I was waitlisted but later got rejected.

I want to reapply this year. Since I still have some time in hand before fall so wanted to utilize this in taking up one or two quantitative courses. My specific questions are :

1. What quantitative courses will strengthen my candidacy for MPP programme in schools like GSPP, georgetown washington and University of maryland?

2. Does it matter from where I do these courses? Community college vs state universities

3. Also my GRE analytic writing was low. So does enrolling in course like critical reading, writing and thinking and scoring A will make up for this low grade?

Your replies will help in giving direction to my endeavours
