I could help. But some things are just specific to a given process. Heck, I did not know BJJ used the term 'Professor' until just recently.
That’s just because ”professor” in Portuguese means “teacher.” I don’t think it’s used so commonly among non-Brazilian instructors. At least, the only people who ever call me professor are Brazilians or sometimes individuals who primarily trained under a Brazilian instructor. Everyone else just calls me “coach” or Tony.I personally find that annoying, but that's just my opinion.
