This is an editorial estimate for the listed foundations and exercises, not a promise of mastery. Familiarity comes earlier; practical confidence requires repeated projects. Strong proficiency often takes months or years of continued use.
At 1–2 hours/day, missed days and revisiting prerequisites extend calendar time. Skills can be studied together.
