Partner, given your score (384, right?), I'm pretty sure you passed. I believe that if you had failed, they would have written something pretty sad on the comments, instead of writting this score. This 'F' is probably a mistake (either that, or you're right, F stands for "Fantastic" ). Anyway, send an email to firstname.lastname@example.org, and explain the situation. And also, say that, if this 'F' is a mistake, they can already send you the certificate.
