Hi guys. I apologize for what's most likely a vague question, but it's something that's been plaguing me since I've started to consider returning to school and switching careers. I'm trying to discern how strong my application would be, specifically for a masters of environmental and energy policy, concentrating in political economy. I have fairly humdrum undergraduate credentials, mitigated by what I hope is compelling post graduate experience. 1. Undergraduate Degree: B.A. in political science, minors in political economy and philosophy School: Temple University GPA: 3.2 (3.5 in-major) 2. Post graduate 5 years managing projects and writing math, science, and social studies content for a digital curriculum provider, and last year I took the GREs with strong results: 169 V, 163 Q, 5.0 AW. At this point I've lost touch with any professors from undergrad, so letters of recommendation would be coming from the professional side. So my question here is, will my application show a strong candidate with good personal/professional growth, or will I be sunk by having middling grades at a non elite university having done work outside of my prospective field of study for half a decade?
