I am just curious about the listing of the 49 word lists in each week's section of the Handout Booklet. I noticed they are a mix of "essential" and "advanced" words. I can't figure out if there is a theme among the grouping of words. I'm just curious as to how the lists were developed. Are they based on difficulty level?
What are some good organizational groupings or methods to sort my flash cards into in order to help me learn the words?
