The courses are heavily focused on science and clinical application of healing the patient. Some of what is taught in Tier 1 is similar to what you have learned as a member of GFS. Tier 2 is much, much, much more in depth. Both come with a pdf download of all of the slides. These can be used as teaching tools. Ther is an essay quiz at the end of each Tier for the pesron to be able to exhibit proficiency of the materials studied. Recipes are provided on this forum and in the Glutenology Cookbook.
Hope that answers your questions.
All the best,
