Note
My perception of why the grad student assistants and prof think today's midterm will be no problem and I'm pretty sure it will be a problem:
The prof is like Igor orienteering. He's in the middle of the woods, but he has at least six tricks at his disposal to tell where he is:
* steepness
* lands shape
* vegetation boundaries
* compass
* approximate distance from his last trail/ap
* runnability
I am like a day one noob that ended up in the middle of the Brighton glacial madness. I only know trails and compass, and even those not very well. I can't even see a trail from where I stand, and it also takes 3x as long to trail every thing. I don't know where I am, so the compass isn't helping.
If I fail the test, I'll try to invite the prof to an orienteering meet.
