There aren't, because JY only uses old LSATs for the problem sets, to leave all the recent ones pristine for full length PT practice. The comparative passages were introduced in PT 52, and the problem sets use PT 1-38ish.
There was a girl in my testing center who brought a digital watch but the proctors didnt say anyyhing about it, despite standing in front of her. Would this be grounds for reporting to LSAC?
