Moving to Canada midway through O-Levels

[Hawk03]

Hi everybody

I'm soon going to move to Canada with PR status. Currently I'm halfway through Grade 10 or O-2 in Pakistan. I'm going to give my CIEs for Pakistan Studies and Islamiat. I was wondering whether I should wait until after my CIEs or go immediately. If I choose to go, what sort of situation will I be looking at regarding subjects etc.

Also, if I have to come back later, will Pakistani schools and colleges accept me without Pakistan Studies and Islamiat qualifications? Or will I have to sit private exams?

Anybody have any advice?

Thanks
