Yeah I took it in December and the guy seated next to me lost his ID the day before the LSAT. He brought a bank statement, DWP bill, and his student ID but they informed him just before the test started that he couldn't take the exam. The guy started crying. It was pretty horrible.
I brought my ID, my current passport, an expired passport, my expired student ID, and some squamous epithelial cells on a Q-Tip.
