“You can that again. :-)”
Obviously everyone can make a mistake every once in a while (as avident from your post)…
But seriously speaking I would rank lower on an IQ test because of my low spelling and grammer skills. (Which in this case is not a sign of weakness in laungauge arts, its a sign of not learning properly the English laungauge [my Hebrew and Yiddish are perfect]). Thats why its importent to have a professional interprate the test results.
