Organic Chemistry

I was wondering if anyone out there has taken or is taking the Intro to Organic Chemistry from UC Berkely Extension online. I have just started taking the course and I was wondering if anyone had any feedback or tips for me. I am taking this in hopes of applying for NA school next year. I know there are a few NA programs that don't require O-Chem, but I figure it is a good idea to have a background in it.
