I did not do well in my undergrad either. I had a 2.77 overall. I was admitted into a graduate program on probation. I had to achieve a 3.5 to keep my assistantship at the school I was studying at. Once you complete your Master's Degree most of the time schools are looking at experience rather than actual GPA. I was not asked about my undergraduate GPA in any one of my interviews for colleges.
The biggest thing in getting a master's or doctorate degree is finding a professor you want to study under. If you are open with that professor they will help you get admitted into the university that you want to get into.
There is still hope for you!
