I finished all my courses at my college as a math undegrad but I don't have my degree, because I haven't submitted my thesis. (It is necesarry to submit the thesis to get the degree.)
At my job, we did a research project, and I'm a coauthor. Everyone else has a master's degree or a PhD, but I don't. For example, my boss finished his courses in a math graduate program and he is writing himself as "John Smith, BMath". How should I write my scholar level?
