GPA - How exactly do you calculate it?

<p>I graduated last year and I am applying RD to the classs of 2011. When calcualting GPA do you include only classes from, in my case, grade 12, or do you include all classes taken in your senior years (i.e. grades 11 and 12)? Also, I am from Canada, BC in particular, and we take a course called C.A.P.P. (Career and Personal Planning). It's kind of a joke, all I had to do was write an essay about your future plans and get an employer recommendation and, in my case, I got 97%. Should this be included in my GPA calculation?</p>
