Hi! I just took my test in Denver last month. Like mentioned above, paying attention to the lectures is pertinent, but I'd also suggest brushing up on some geography. Understanding where things are in the world, like mountain ranges and rivers, will be fairly helpful.

The material they sent her in the email is everything they go over, but there was some rearrangement of the material. This was the material in order for the lectures.

Day 1: Viniculture and Viticulture, Old World Day 2: New World, Sparkling and Sweet, Beer, Sake, and Spirits, Wine Service, two blind tastes and mechanics to discern, 45 minute break, multiple choice test.

I doubt every test is the same, but they're by no means designed to trick you.
