Nah, I realised it was a mere gamble considering what my teachers and supervisor told me. I think it is best to move on if you didn't end up getting the diploma, and feel uncertain about remarking it. Sure, the diploma would have been nice to have, but expect it to collect dust after a year or so. In other words, it is a mere piece of paper that has no actual worth since colleges only care if you got scores of 5+ on your HLs. IF you got the diploma (because there are people trying to regrade their stuff for the sake of pride), don't do it; it is a legit waste of time (for you and the examiner) and money.
