Aloha Alexandra10,
Don't worry about this aspect, as it is an enhancement of the work you do in the Essentials, Level One, and Level Two courses.
Take you time and go through he Essentials course, working with what you can and appreciating what you can't, and move on to Level One.
Every little bit helps, so don't worry if you are not as far through the course as you think you should be. Feng Shui is an unfolding process.
Much Love,
Shawn
