So it's been awhile since I have graduated from my undergrad. My university did not have the standard 4.0 grading system and all the courses were to be graded with credit/no credit. I am trying to use Law School Predictor on 7Sage, but without knowing my numeric GPA, I am having a difficult time selecting my options. Could someone help?

I really would like some motivations and have this opportunity to share some ideas for LSAT and applications. Let me know!
