What IS this? Seriously, how does this make any sense?

We're waiting for our grades, so we check SIS every day to see when our professors stop tipping back the shiraz and get around to posting our grades. So, when they finally do, instead of showing us our marks, the system...locks us out because grades have been posted? Whaaaaat?

Susan Russinoff!? Logic taught me that this makes no sense! You may be the lowest grade on my transcript that I cannot view right now, but for christsake, I'm antsy. BAH.
