Are you applying to school in the United States? If so, you have an excellent chance. Remember, test scores are only one component of school admission; actually, it is the bottom of the list. The school will probably also look at your general GRE scores, but first it would look at your GPA, letters of reference, academic standing, and personal statetement before it would look at your test scores. Don't sell yourself short. Assuming that you don't have a shot might actually be defeating, since the process is somewhat self-selective. Take heart! It sounds like you aren't looking to get into a top 10 school, anyway. It sounds like you have a good chance of acceptance.
