I feel the need to say you guys are really over thinking this. We aren't the selection board, quit trying to come up with all the right answers on here. You have already made it. You have three years to finish, period. If you push through and get done quickly good on ya. You get commissioned sooner and fly sooner. That being said, the instruction never says you need to get done as soon as possible it says compete requirements in 36 months. I would really like to get back to the fun stuff about this program, seeing where people are going and getting psyched about Boost and/or NSI.
I could care less how long someone takes to complete their degree, but I guess it's up to ones interpretation of "proportionately reduced period of time."

e. Following completion of NSI, all participants will enroll in college studies. Enrollment may begin as early as the summer semester following selection notification or later depending upon assigned reporting date and program option. Based upon college-level credits already earned by STA-21 participants, advanced academic standing may be granted at the discretion of the individual university. Students so advanced will be expected to complete degree requirements in a proportionately reduced period of time.
