I think that one of the most important aspects of language learning is simply organizing yourself, and keeping track of the words that have been learned.
I like physical flashcards, but I’m always afraid that I’m going to lose a word! It is also impractical after learning a few hundred words of a foreign language.
I have tried some free online flashcards, but the ones that I like the best are from BKYI.com. BYKI stands for Before You Know It. The flashcard system that they use tests users on several different levels (review, recognize, know, produce, own) it give you the ones that you got wrong more often then the ones you get right. I also find it very motivational that when you clear a level it plays victory music!
The company offers BYKI lite, which is fully functional with 90+ lists, the only feature disabled is the ability to add your own stack of flashcards until you’ve purchased it. I like the premade stacks, because they are organized by topic! It’s a great free product for beginners, and definitely worth it to buy it once you are at an intermediate to advanced level.
I would like to ask how other language learners are keeping track of their words. Do you use an electronic flashcard system? excel spreadsheet? a diary?
