When we learn a language, I believe everyone has been through many tests and practice to make sure we have memorized them all.
There is a science research which shows that people need to memorize one word for a long time before you read and see them 21 times.
This free version app divides into 5 units for you to study. However, you can note them into “Don’t know” or “Vocabulary” category in the same time you test yourself.
Next time you want to review or go to test again, you may directly go into the “Don’t know” part to learn again. It shortens the time you need to go through same units all over again. I appreciate this kind of design, which makes me clearly know what I have really learned so far.
