Ôn OSG

The videos is for arvhive.
Note :
+ Videos from before "HK5" won't come with homework or resource files as those videos are the old ones.
+ Videos without ordering numbers mean I'm not recording consistently for that class! (though I will try to upload it in the right order when i "recorded" (a.k.a the last time I edited the video file) )
+ Videos volume might be small as I record the browser by OBS (I don't know why this happens)
