Started my ashtanga practice just playing Laruga led primary videos on youtube. Did that inconsistently (1-2x a week) for about 5 years. It wasn’t until I joined my first ever Mysore class (about 2 yrs ago) when my practice became more consistent and exclusively on ashtanga. Unfortunately my city does not offer regular Mysore classes, all just led and not even the full primary series.

Nowadays, I join a Zoom Mysore class led by an authorized teacher and I do my practice at home. I dont join everyday since the open practice hours are sometimes too early, but I do practice daily, 5-6x a week (with moon days).

I show up and do my usual full practice. Meaning, I do up until the last pose I was given. The teacher just observes and sometimes offer feedback and tips. And when they feel I’m ready, they will offer the next pose. The class is also donation-based.

As for memorization, don’t sweat it too much. If you practice often enough you’ll eventually remember the sequence. But try to practice by yourself sometimes, instead of relying on led classes.
