Testing Understanding From the Other Side

Just this morning I managed to create an 8 question quiz and made three of my peers take it.
Here's my aftermath and my thought process.

• The questions that I chose were ones that any person who was paying to the book would be able to answer, they were simple enough yet required so memory digging. Most questions were about the characters and what roles of importance they play in the book.
• So far those who have taken the test managed to each get 100%
• this shows that they were paying attention to the reading and the dialogue as well as the characters
• they were able to prove that they understand the plot so far and didn't show difficulties to any of the questions
