One of the things I played with during my revision was Anki. I decided to just chuck any new word I came across into an Anki deck and see if I could try and get a few of them to stick. It’s actually really good. Better than the old version of Memrise, in fact, and I was really salty when that was scrapped. I like how it let’s you choose how easy you felt the card was and it’ll use that to gauge the time before your next spaced repetition. It means less time wading through lists of words you know to get to the ones you’re really struggling with.
