And I've got no idea what half your post actually means...
I'm fine with grammar and can usually construct a sentence which is spelt correctly and has correct grammar. It's just that I've never really been taught it. I've just had to pick it up as I go along from what little I was taught and books I've read.
It's weird, I just sort of know if a word is spelt correctly or not. I actually quite good at knowing the spelling of words but I have to write or type it first though. If you just ask me to say it then I'll have trouble remembering. *shrug*
