One concept that I’ve known about for a while and that I have been implementing for my studies is spaced repetition.
This is the idea where you space out your studies in an optimal way so you don’t waste time with your studies.
You review the information right at the point you are about to forget it.
I’ve been using the flashcard app Anki for many years for my Korean studies in the past.
So what I’m doing with audio lessons is that I’m going to space out audios from 2 Japanese lessons playlists – Minna no Nihongo and Cure Dolly Japanese.
