A recent change on the home page is to add the Average Level and the Words Mastered to the home page display.
Previously the home page displayed just the Words Known as follows. The problem with this however is that it gives no indication of whether the words are well known (i.e. have a level approaching 10), or are only very slightly known (i.e. have an average level nearer to 1).
The new display, shown below, makes things clear by adding the Average Level and the Words Mastered. This is particularly important as in the end it is not just about the absolute quantity of words that you maybe only vaguely remember, but also about how many you know really really well.
I hope this new Lingopolo addition helps to motivate you to better and better Thai mastery!
