IF
The student completed more than one program from an eligible DLI within 2 years.
Note: Each program of study must meet all PGWPP eligibility requirements and be at least 8 months in length.
THEN
The length of the work permit should combine the length of each program.
If the combined length of the programs is 2 years or longer (or 1,800 hours or longer for a combination of a DVS with an AVS in Quebec), the work permit may be valid for up to 3 years (provided that the DVS program in Quebec is at least 900 hours in length).

You say : "The programs need to be completed within 2yrs. "
So, how it is contradict written above and what lolcocks said?
What do you mean by this: "I've finished a 4 year and a 1 year program at two schools "? To take a 1 yr program with a gap of a year or two?
Because if you finish your 4th year in April and go to the Uni in September again, it means "within 2 years".
