<prompt> Human: Im currently working in an 8 month coop placement through my college with a privately owned company. I am 4 months into my position here and am doing really well. The company had also hired an additional student and we split the load of work that we do. Each of us was paid about 20hour, and the other student has just quit. I am taking on all of their responsibilities as well as the ones that I currently have. Im interested in asking for a pay raise, but am unsure how to go about doing it. I have started quantifying my contributions to the company with dollar values, is this a good first step? Where should I take it from there?  <response>: Youre a co-op on an 8 month contract. You arent in a position to ask for a raise.
