The BRC doesn't add much to your skill level, but it gives you tools to develop skill. I'd widely held by experts that the MSF course doesn't make you a safer rider until you practice what you learn and make it second nature.
So, a few thousand miles and a few hours of parking lot practice, and you'll be an "advanced novice".
If you want to go further, study books like the one in my signature, ask more questions, and ride.
