Hi mmm22,
I have a 3.83 CGPA in a poli sci degree. I have no relevant experience, though i did have some minor volunteer work throughout my undergrad. I explained why I lacked experience in my SOP though (working 25 hrs a week and finished undergrad in 3 years), and even though I mentioned I would like to do coursework, I explained previous area's of academic interest and my desire to participate in the coop program. As well, I am confident that I had strong letters of recommendation from two well-respected profs who know me fairly well. Compared to everyone else's experience, I am now even more surprised I was accepted though haha
