Hello! I would like to ask those of you who have completed the course 2 test if there were a lot of questions that focused on modules 6-8? These modules include a lot about house structures, styles, energy efficiency, water wells, sewage systems and house components. They are pretty extensive in content, but I haven't seen anybody say that they were a big part of the test. I have even seen some people say that they spent a lot of time studying those modules only for 3-4 questions about those modules to pop up. Can anybody give me some insight on if these modules are something I should spend a lot of time studying?
