Example punctuation and how a sentence is written etc. I can read and reread and a sentence seems fine to me although someone who's smarter (teacher/student getting A's in English etc.) says they can't understand it. In my brain no matter what it makes since TO ME! So I was curious if others on the spectrum had issues like this just curious.

I would say my grammatical skills are "average". Although at times, I'm a little unsure about my punctuation. My spelling is TERRIBLE!

I use the spell checker constantly.
I know when I proof read a paper, It helps for me to wait and proof read it a day later. I find that I discover a TON of things I missed the previous day.
I wouldn't call the people who have better grammar "smarter" than you....even if they have better grades. It just means that they have a more developed ability than yourself. I'm sure there are many abilities that you may have that those people do not.
