Actually, that was not a typo. A typo is inadvertent. Using "loosing" instead of "losing" is a rather common event these days. I see it so much, I have stopped pointing it out. This is not to impugn your intelligence, but one should be sure that the choice of words and spellings is correct when commenting on education, lest one became an example supporting one's own argument. Another point is that a spell check will totally miss this, and spell check is no substitute for a proper education. (I'm being very careful to use correct phrasing and proper spelling and punctuation right now. How did I do?)
I have a spelling checker.
It came with my PC.
It plane lee marks four my revue
Miss steaks aye can knot sea.
Eye ran this poem threw it,
Your sure reel glad two no.
Its vary polished in it's weigh,
My checker tolled me sew.
