BjjBrick Q&A Q17 Help with lacking a BJJ curriculum

Here is the question:

I started BBJ 3 weeks ago and love it. The only thing is there isn’t a curriculum, starting course, or even drills…. I just go, learn some moves and roll. As a white belt, I’m trying to breath, be safe, and learn the fundamentals… but I am not taught them exactly so I have started using youtube Gracie videos… I want to keep showing up and putting in work to show my coach how motivated I am to learn this art… but I’m not sure if I should bring up my problems now or later…
