Canadian vs. US CASPer Evaluation

Hi all, I took the Canadian (English) CASPer two days after I took the US one. I was surprised that I scored two quartiles more in the US exam than in the Canadian one. Does anyone else share this experience? What do you think were the differences in evaluation between the two versions? For context, I went to middle school in Québec and graduated from HS and college in the States.
