I almost forgot:
An exam I did for programming in C, I had an email about. When we did it, we did it in two groups (not enough computers for all of us at once). I was in the first group and we had some very serious slow down issues (it was taking up to 2 minutes between clicking on some text and the cursor appearing, 20 minutes to print etc.). This was fixed for the 2nd group.
Anyway, the email informs me that I can either choose to resit or to get a 5% increase (though I can't see my mark till after the choice). The great thing is is that apparently, the first group did better than the second group anyway
I think I will be taking that 5% on top of my (probably) above average mark...
As an aside, these problems are the reason I will punch anyone who says that Macs don't go wrong.
