I'm crushing biology practice dat tests, but I didn't do so well on practice cDAT questions

Dec 5, 2014
Canadians can only take their test on two dates (nov and feb), so at the moment i have about 3 more months before my dat. I've been practicing and doing well on bootcamp and genius tests (25-28), but when I was trying out some of the practice questions in the cDAT biology section the questions just felt a bit trickier and a little more "random". Can anyone who's also taken the cDAT let me know what's going on with this? Should I stop practicing with american resources like datgenius/bootcamp and try to find more canadian resources?
