Read through the list. These are pretty easy to learn, based on all the rules and principles you have leared so far. There may be a few that require additional study.
Remember, like the cities and towns, you don't have to memorize all of these. Just read through the list this week and in your "homework" next week you can try to write them from dictation, again remembering that you don't ahve to memorize all of them. You may never have to use the word "architect" in your life and if you do use it on occassion you can write it in full. However, words that you do use now, learn thoroughly. Refer to the list when your life changes and you have a new endeavor so you can learn what you need to again.
"Gregg Shorthand had achieved the most extraordinary success ever attained by any system in the history of shorthand." John Robert Gregg, 1922
