I had an extremely low GPA in undergrad (under 3.0), and I also had very low GRE scores (verbal 146, quantitative 144, writing 3.0), so of course I figured grad school would never happen for me! I decided to take a post grad CDA program (similar to SLP-A but in Canada) and ended up with a 3.8 GPA there, and worked as a CDA in acute care for a year while I tried applying again, I am now halfway through my first year of grad school and enjoying it very much! I was really surprised to get accepted but it is possible!! Good luck!
