If you practice the drills 5–10 min/day , most people notice better control in 1–2 weeks and a functional migration to Frenzel in 2–4 weeks (depending on your starting point and consistency).
It's not mandatory. A nose clip and a mirror/camera for feedback are helpful, but you can start with just your body and the course materials. For water activities: always with a certified buddy.
