The kingdom of Judah had 20 rulers–19 kings and 1 queen. Of these, 12 were wicked, and only 8 were righteous. Two of the 8 turned wicked late in life. Now you can easily memorize all 20 and also learn of the last Son of David, who remains King forever. When I was in college, I had to memorize them the hard way. You’ve got it easy! Knowing these kings will give you additional structure to your studies in the Hebrew Scriptures.
