15 or 12 hours is a full-time study? HELP

[mjsantos]

Here in the US, if you take 4 classes with each one being 3 hours, that means you are taking 12 hours of study every week. It is considered full-time studies here. Will CIC consider it full-time or should add all classes I have taken in college and add up the hours and divide by 15 to find out how many weeks I was in school as full-time?

Thanks.

It would take a student 4 years. However, I decided to take some extra courses for knowledge. Then, it would take 5 years because of those extra classes. Should I take it as 4 or 5 years as full time?

Thank you.
