Can I Continue Studying on a Post-Graduate Work Permit?

[chrisyoc]

I just recently finished my B.A. in History at Dalhousie and applied for a Post Grad Work Permit. I have a valid study permit which expires in Aug. 2012 as as well as an off campus work permit. I am waiting for my PGWP and working as an insurance agent full time, but I also applied for Jan. admission to a Private College to take classes while I am working full time towards my PR. Will I still able to study on my PGWP, or does my study permit become void and thus I can only work?
