If you are, like me, fascinated by this "old" tool called the abacus, or specifically the soroban, you've already managed to get your hands on a soroban and began to practice and learn how to add, subtract, multiply and divide with it. If you need reference, try  and .
I have learned to use the soroban with the help of the very good book Le boulier, Initiation  by Jean Cumin and Jean Hossenlopp (published by Chiron in french). I have also read The Japanese abacus, Its use and theory , the book of Takashi Kojima. These 2 books talk about the soroban examination   taking place in Japan for each grade, called kyu. They show example of these examination and it's a good exercise to do these to practice and improve your soroban abilities.
So, I modified the little generator I already did for me to produce pdf files of these examination exercises. You'll find below screenshot of how such documents look like. To see a real example, just go and try the generator.
