For years I couldn’t learn French vocabulary. I’d make lists, make cards, buy cards, and nothing really would stick.
Especially over time, the vocabulary would evaporate.
Frenchpod101.com changed everything. The reason is their turn-key system of spaced-repetition vocabulary study.
It automatically serves up the cards I need when I need them.
So, I pretty much never forget a word. It’ll remind me just when the average human brain would start to forget. Even a year or more from the last time I studied it.
It also allows me to push through the “natural” spaced-repetition schedule limits when I choose to. So, I’m free to accelerate the process and install hundreds or thousands of words in my brain, so to speak, early. (Then maintain them.)
