Hello ;)
The trick to earn a lot of xp is to use the combo counter for vocabulary... It can go up to x10 o_O

Since you have completed vocabulary level 1, you can use the settings button in the practice section to set the questions to vocabulary level 1 only... ;)
That way you don't have to worry about things you havent yet learned...
