Yesterday, Mom took you to take the third-level Japanese exam. Hehe, let you get a taste of what an exam is like early, and get you fully prepared for countless exams in the future. To be honest, your mom didn't prepare much and made a lot of basic mistakes in the grammar section. Because this person actually knew the answers but hesitated and ended up choosing the wrong ones. So, your mom felt a bit regretful and down. I wonder if you realized that?
