I read an interesting article today, so I'd like to share it here with you.

The best time for doing review is before you sleep, and when  you get up.

When you are sleeping, you can retain your memories very easily.

So please try to review at that time what you studied during the day.

Human memory tends to lose half of the content after 20minutes.

So it is better to  retain your memory to review after 20minites, one day, one week, and one month.

I will try to review like this!!
