Thank you for the forum and your help!
I need some advice for my course. I made a course of German, it has 27 levels of words and expressions. The first levels include very simple words, but I need to repeat it time to time anyway. Maybe do you know, how to include these simple words from first levels and “long-term memory” mark to daily repetition with new and difficult words? For example, 20% simple words and 80% new and difficulties. Because the words with ‘long-term memory’ mark could be also forgotten.
Thank you in advance!
