I tested my knowledge of the Russian language and got a solid B. Go ahead and test yourself?

The suffix "chik"? Is this a joke? Isn't it in the word "shkafchik"?
P.S. The schedule is very funny. :)

Ah, it didn't display here... And on the website, they wrote to me that "The suffix 'chik' is apparently too difficult for you" :(
