I don't think so,
becoz the syllabuses just change (05 CE and the coming 07 AL)
and their colourful notes always state that they met to the most update syllabuses,
so I guess they record the videos every year.
P.S. 1: KG's Mong Kong 168 centre (M1) closed~
P.S. 2: Modern will open a new centre in Mong Kok soon~
