Having the chance to create my own test opened my eyes to the multitude of information learned in chapters 1,2,4 and 6. By developing questions to ask I was able to understand more thoroughly the concepts that were discussed in the classroom lectures and in the reading. Also by having the opportunity to design this test I was able to form connections with the material learned over the beginning of the semester!
