I took my PF 1st semester finals on 9/15 and my proctor mailed them that same day (handed it to the mail carrier as they were delivering nearby). The postage is prepaid so I didn't think anything about it. Well I called PF today and they haven't received my finals. I asked them to double check and still nothing. Now I don't know if it's lost in the mail or lost at PF. I asked them what I had to do if they're not found. Of course they said that I'd have to retake. That is the last thing I want to do. But I'll do it if necessary. Has anyone else had this happen to them? I can't believe my luck. My main question is how long should I let this go before I just throw in the towel and retake? Or do I have any other options? Next time I'm sending it express with tracking capabilities.
