whoa what happened?

I got my IB grades. the good thing is I met my offer. the bad news is... whoah theyre bad! I was working at a level of 1,0 (german grades) the entire past two years, and now Im walking away with a 1,7?! whoa thats weird. I mean on the one side its weird, that EXACTLY Imperial is working. and nothing else, like something leading me there. On the other hand, I simply cannot believe the exams went so bad. Like I NEVER got those grades before. Oh well. Im in uni, and thats all that counts, and I can stick my personal pride elsewhere because, well I just gotta live with it.
