In Australia, children undergo twelve years of formal education (plus Preschool, Kindergarten and/or a preparatory grade or Prep), usually starting at age four, five or six, and finishing at age 16, 17 or 18. The Years are numbered from 1 to 12.
Modular PSUs are also referred to as Full(y) Modular, and semi-modular ones are usually just called Modular. Sometimes you get less cables than your modular PSU can accept, Enermax (for example) love doing this.
