I checked and own up to my mistake. The discussion of repeating the entire year was discussed late January/early Feb. But instead, the HK education board opted to rather squeeze several exam sessions into single days. My wrong. I stand corrected.
Hhmmm, care to post a reputable link that supports your claim ? HK students have been studying online for a while now, not only I saw short clips of my wife´s nephew studying online, but that´s what google also comes up with. Can´t find news about the kids having to retake the entire school year.
