exam fatigue

I am beyond bored of these exams. Last night's revision was geography. I feel I should perhaps sit the bloody thing myself now. With my extensive knowledge of ageing populations and urbanisation I'm well on target to get an A*.
But at least I'm not on taxi duty today. The school is a 15 minute drive away and yesterday I went  three times. THREE TIMES! And back three times! That's 90 minutes actual driving time. Not to mention the time sat waiting outside school like an idiot while she catches up on the goss with her mates. Like I don't actually have a list of work as long as my arm to plough through. 
It's German tomorrow. I can tell you now I am not gonna be any help whatsoever in THAT revision sesh. Think I'll go out tonight...
