I was wondering if anyone knows how your undergrad GPA are weighted compared to a Master's degree GPA? I had a realy low undergrad GPA, a 2.8 and got into a one-year Master's program in Molecular Genetics. Did decent there, a 3.7. Do you think that is more important than the undergrad one? I'm applying to a Ph.D program in Immunology and looking at some top schools like Columbia, Duke, and then some middle ones. My GRE is also decent, 1380 and I took a year off to work at a research lab at a hospital and got published though not first author. Thoughts?
