This even is full of A&S activities and will offer a number of classes on a broad range of topics. http://www.gulfwars.org/activities/arts-sciences-2/classes/
In addition to that classes listed in the event materials, there are often additional classes that will be held onsite. This year there will be a series of Viking and other early period classes held in a dedicated space set aside by the merchant Feed the Ravens.
The class list downloadable at the link below (as the image might not be large enough to view from some devices). I highly recommend not only checking out some of these classes, but checking out the amazing wares (often with a high level of authenticity) offered by this vendor. They are also very nice people which loads of knowledge and experience that they love to share!
