Students finished a lesson and when they come back to it, the bars in the lesson went down. Why?

Word strength "decays" after it's been a long time since we last were exposed to them. To keep the word strength in tip-top shape, we recommend practicing and "strengthening" the skills with practice. So the gold tree does not stay gold forever. ;]

It is probably because they didn't do so well, not that I am saying your students are bad, because if they got many questions wrong then they will need to strengthen them to be able to remember them better.

Will they go down even if they were gold? When do they stay with all the bars?
