Ha! I had to write the LSAT in a large lecture theatre, with "flip up" writing tables rather than actual desks, which gives you very little writing surface to work with.
I was well aware of this long before today, but while the proctor was reading out all the instructions, this guy in my room puts up his hand and starts ranting about how we had to pay $150 to take the test, so why wasn't there adequete writing space in the testing room, etc. etc.
And then, 3 minutes into the very first section, the proctor walks up to me and was like,
"I'll take that for you and put it up at the front with your personal belongings", pointing to my timer. I said "you mean, my timer?" and she was like, "oh, that's your timer? Sorry." That kind of threw me off, and wasted a precious minute at least
Otherwise, things went well
