I wish I can find the archived training courses.
I am now looking for Unreal Engine Training 2020 https://cdn2-unrealengine-1251447533.file.myqcloud.com/training-fall2020-noappendicesv4-adfd1cc70381.pdf.
I missed some classes due to the enrollment limitations. The box link I got is like https://epicgames.ent.box.com/s/yxxucsu1ui1spb1xuais6z8wg4u6rq59. Really want the full class archives.
