It seems Symantec is developping a basic training which should be released in a few months. As Consultant/Trainer I am looking forward to this and I am very curious in the depth it will go. But you have to wait for this.
Another way is to setup a knowledge transfer with a BESR consultant. This setup can be a class-room with some custome developed class-material (can not be Symantec study material as it is not allowed) or you let yourself be assisted in your day2day job with BESR to see if you can do things differently/more efficiently.
Hope this brings you something
