Yes - but isn't the non-US one the one that has metric measurements? I don't want him to get confused using metric if the then has to switch back over to USA curriculum standards and measurements. After all, there is a chance he'll have to go back to school at some point - in which case - I'm trying to make sure that he covers the State's requirements as well as has the oppotunity to go deep.

Does anyone ahve the link for the pre-assessment. I finally found a decent PDF version of Saxon's but not Singapore's - put it down to sleep deprivaton and working full time on top of trying to roganize home school curricilum (or you know, we could just conclude that I'm not too bright...)
