Its out of 20 apparently.
I got 16, which is pretty annoying, but i should get over it soon. As long as i can get into Barts-Architecture next year ill be happy.
There doesn't seem to be any stats available for the quiz though, so i don't know if 16 is actually good-ish or shite-ish. Most probably the latter.
Now, i am still waiting for the philosophy results. Get to work markers!
