DL389
The MSF office you used should be mailing you DL389 to you within 7-10 days. With this in hand, when you go to the DMV, take the written test, and if you pass, you get your M1 endorsement on your license, (you do have a drivers license right?). This is only the beginning. You just took the BASIC riders course. Keep practicing. There is an experienced riders course in which you use your own bike, but you must be riding for about 6 months and have a couple of thousand miles under your belt. Now zoomzoom, a track-day company, has a new program they are starting up for those wondering ' what now after I've passed the BRC'. This is a new program and there is little info on it, but you can check it out on their website.
Good luck and be careful
