Videos mapped to the different syllabi. The best source for these is YouTube, but it is not universally available around the world, so to help out I've downloaded publicly available videos, whilst also including the original YouTube link.
Most will also have a .srt file, which if you download should allow you to get English and sometimes Chinese subtitles if you donwload them to the same folder and use a video player like VLC (the dominant open sourced free player)
A great place for extremely throughtful and well made videos is this YouTube channel: Kurzgesagt – In a Nutshell, which, if you can access it, is here
Core videos contain essential information necessary to do well on the exams
Extension videos are more challenging and are better suited to the more interested student
