Us'got good gramher? test there are http://www.termiumplus.gc.ca/tpv2guides/guides/pep/index-fra.html?lang=fra&page=../toc

Wow, took some of the tests... I don't claim to be great with grammar, but I feel I AM better than most people I've worked with over the past 10 years... having said that, the pronoun test, which I presumed would be simple and straight-forward, proved harder than I thought... my my use of "I" and "me" is apparently not spot on.

I think we've had disagreements about that before.  The bottom line (rule of thumb) is, when you break it down without the other person in the sentence or rearrange the order of the words , it should still make sense.  Take for instance, for the test question: "My teenaged neighbour knows more about computers than (I/me), even though I have been using them longer than (he/him)."  It would make sense to rearrange the order to say "I know less about computers than my teenaged neighbour...", rather than "Me know less about computers than my teenaged neighbor..."

Likewise for the question "The mail-order company sent Maddie and (I/me) a free velvet painting, but (we/us) girls, having some artistic taste, shipped it right back."  If you were to ignore Maddy, you'd say "The mail order company sent me..." rather than "The mail order company sent I..."
