The Invoice1 WOD taught us how to create a basic sales invoice. We used five different example items and made the invoice by using JavaScript and HTML. You can view more deails of the wod here. My first attempt at Invoice1 went smoothly until I got to step 8. I had to watch the screencast solution to understand what to do because I could not understand what the instructions were saying after re-reading them a couple of times. To prepare, I use my first attempt to practice and see what I need to study more. I do not time my first attempt because it makes it really stressful for me. When I end up watching the solution, which I had to do this time because I could not understand step 8, I usually understand what has to be done after that. Next time, I think I will try go over the readings more in hopes that it would help me understand the instructions better.
