22 Sep 2019 - Latest and last video before end year exam from JJJwong

Javier has been posting his youtube videos on a weekly basis.  Today he posted his latest video.  I find this particular video very interesting.  Click on it and enjoy!
At the end of this video, he informed his subscribers that he will take a break from creating more videos till his year end examination is over.  Very sensible kid for knowing his priorities.
