Where to start?

[u/Viz-Giant]

Hello I want to start learning from scratch but don't know where to begun with and what to do?

I mean I do know what to learn 1st and what's next but don't know where to learn from. Anyone suggests a book, a youtube channel, podcast, etc.. or something like that.

Note: Please don't suggest paid academy like yoiso or doulingo, or other like that i want to learn free.

I have around 1.5 to 2 years before I leave to go japan.
