I think it shows attitude and asian-ness when you write it as "oPtOmEtRy." You're bound to get in!
I don't know what it is but students these days can't read or write cursive and cursive is in decline. So professors have to resort to printing out individual letters on the chalkboard. And some professors write in all CAPS but every once in a while, they'll lower case a letter and I always get pissed off at that. C'mon, show a bit of respect for the English language.
