I think it is pretty straightforward: "Completed 60 percent of full-time course load for 1 year" means, if you have to have 12 credits to be considered full-time (what is considered full-time for financial aid) then you have to complete more than 7 credits to still be in the program (7.2 is 60% of 12). So, if you are taking 4 courses of 3 credits each, you would need to complete 3 of those 4 within a year. The rub is that you cannot just take 1 at a time because then you would not be full-time and there are a couple of semesters in the year so you would have to take 4 courses in the Fall and 4 in the Spring and pass at least 3 each semester. It generally takes 15 credits a semester to finish a 2 year program in 2 years.
