It was a 1-1/2 day event when I did it. There was some loose coaching on day one sprinkled between the questions we were asked. I gave some doozies for answers(!) There was a sheet of paper with some questions on it to fill out at lunch on day two, to check something about our knowledge level. After lunch on Day 2 our scores were tallied by the examiners. Then around 2:00 the announcements were given of who passed (everyone) and we were given our pins with a great deal of fan fare.
FWIW - I did my L1 in PSIA-East and it was a 2 day event (4 seasons ago). MA and teach were each about half a day and then a day was spent on skiing tasks (I don't recall how that was broken up). L1 in PSIA-RM is a three day event.
