How many additional points I will get for my education?

[Kelvin08]

Hi,
I have a 3 year advanced diploma (with co-op) from a Canadian college. The letter of graduation states:
- Official length of the program is 3 years.
- Number of terms: 7 (2 of them are co-op)

How many additional points will I get for this educational credential? 15 or 30?

Most likely its 30, but I could be mistaken.. I am pretty sure they count co-op as academic years as its under study permit.
