Our classes are self-assessed. We don’t grade you beforehand. With that in mind, please read the class descriptions thoroughly, and seriously consider whether you have the prerequisite skills.Getting in over your head is a lose/lose undertaking. If you lack significant prerequisite skills, you may be asked to audit only, so that attention is not taken away from students who are prepared. This is solely at the discretion of the instructor, and there are NO REFUNDS.
