Somewhere around half of the slides in each lesson are the explanations of the topics. Graphics and pictures are used. Those slides come first. If you will spend as much time as you can on those, and get a general idea of what they are talking about, you will then be well prepared to come to the class. Don't get discouraged because what we will do at the class is go through the second half of the slides, explaining as we go, but it is condensed. Anyone who has been through the first set of slides will be able to pick right up on it and understand what we are covering.
