Good job on listing the areas covered. For more intensive study you may consider also including a brief statement of explanation for each item. This will help the teaching to be retained better.
You are also recommended to visit the Archives Tab and go to L1 archive ending 3/31/15 since many of the beginner lessons are located there and you will gain much from my replies to them..
In reference to Polarity you may also consult the new book MYSTERIES OF THE KYBALION —although this is a fairly advanced text still you will gain from it in reference to this important topic.
Additionally, in the upcoming Neterian Conference (in December) and a currently proposed Fall Semester course the topic of polarity and depolarity will be discussed as it relates to another aspect of the Neterian teaching.
