Welcome! As mentioned, if you are brand new to riding, take the course. I have taken the BRC once and a few other courses offered by the msf because it is a military requirement for me. I would say if it's your first time, it is worth it. There is always something to either learn, refresh, or reinforce at any of the courses. For me though, I get to attend for free. If you are paying for the advanced rider course or ERC, I suggest just taking that money to buy a track day ticket. It's so worth it, and even though it's not a "class" you definitely get some riding instruction if you go with a good track day org. In my honest and humble opinion, I learn far more how to ride a bike from track day instructors than what the MSF teaches me. The MSF is tailored more towards safe riding on the street, not really knee dragging on a race track. Two different scenarios.
