I'm pretty good with spelling and grammar. I think my only problem is that there are a few words that I occasionally spell wrong and it's always the same words. For example, I'll usually put two c's in "necessary" accidentally or I'll leave out a letter in words like the e before the a in "interchangeable". My own secret problem is that I'll occasionally write words that look like, sound like, rhyme with, or are similar to the word that I actually want. For example, as I was writing this and wrote "words", I actually wrote "weird". It's some form of dyslexia, I think. I'm not sure. But it's something I've had for a long time. I've gotten used to proofreading everything I say, though, so it's rare that these ever slip through. That is, unless I'm IMing or something similar, because I never notice when I write the words wrong and I don't proofread IMs unless it's for a chat for class or something else important. I graduated college a while ago, though, so it hasn't really been an issue anymore.
