A few people who are in programs right now say I have a decent chance, but the more I look around the more worried I get. Here's my profile: 26-year old clinical research coordinator at a hospital. I do regulatory work, help doctors interpret study protocols, and report data on patients who are on clinical trials for new cancer drugs. Undergrad: University of WA 2006-2010, BS Molecular biology 3.04 GPA Calc I/II = 3.0 Calc III = 2.7 Currently taking linear algebra, can't understand a word the teacher is saying so we'll see how that goes. GRE: Haven't taken but based on practice exams I hope for ~160Q / 160V What I've done since graduating in 2010: Worked in a government immunology lab for 8 months (which is when I realized I wanted a new career), taught English in Hong Kong for 4 months, took a certificate in clinical trials course at UW while being unemployed for 6 months. Then I got my current job, which I've been doing for 1.75 years now. My personal statement will basically say - I grew up on an orchard with no idea what I wanted to do. Thought I wanted to work in a lab, but realized (especially in Hong Kong) that I need to work with people. Clinical trials turned out to be really interesting and I love that you get to work on various projects with doctors and scientists, therefore biostats would be perfect since you get to work with them and really have an impact/be needed.
My quantitave background is limited though and programming knowledge is zero. I'm considering waiting until next year so I can take a stats course or something.
