Question #6 asks for the total hours the PM could work in DD, not how many additional hours as your answer suggests. The work plan already calls for 72 hours in the DD phase, so the answer should be 72+6 = 78 hours.
for question 2, the explanation as to why a design-build as an incorrect choice is problematic. the presenter explains that there is no "bidding" in a DB, which is only partly true. an owner can put out an RFP for multiple Design-Builders to bid on. the difference is that the cost of the work is based on an RFP or perhaps less developed design documents. this introduces risks to the Design Builder and thus the contractors quote might be higher/inflated, or the Design-Builder has the ability to substitute lower quality materials/products in order to keep the project within budget and prevent losses.
Question One: "round to the nearest half hour" : $6000.0/$140 = 42.8: 42.8/16 = 2.67 rounded to nearest 1/2 = 2.5: 2.5 * 140 = 350/week: 350 * 16 = 5,600

Thank you for your case study. So many factors wasting our time needed to take the exams successfully. Not a good idea.
