I would highly recommend attending these classes. I attended about 80% of the classes, I"m taking the exam in two weeks. The classes allow you to evaluate different beers based on styles, while practicing your feedback, working on quantify your observations, use descriptive language, and best of all, share out with others in your class. I will do great on the tasting portion of the exam thanks to my classmates and our Master Judge teacher. Good luck and have fun.
