Sorry...but honestly, I have never heard that different tests of the same level are being administered in different locations.
Maybe people in Singapore (12 hours difference between Montreal and Singapore) might benefit from some information about the test shared by some crazy Canadians/Americans or Europeans. Otherwise, if it can be done, then those tests administered on the next day (for Singapore, Far East and Australia, if I am not mistaken) must be different...that I don't know and I don't care...
Well, anyway I wouldn't benefit that much from this information, given that I haven't been preparing myself for test before and I live in Singapore or wherever the test takes place on the second day
