Can you help me to find grammar errors in my diary. Today, I bought two books in Aladin.(the Online Book store in Korea) One is the Fluent in 3 month written by Benny Lewis. the other is a Mind for Numbers written by Barbara Oakley. but I felt a little sad. because i was able to buy the used book Fluent in 3 months 3 hours ago. But it was sold. I was able to save the book price 60% of money. After regular class, my home teacher said us "You'll be able to go home. the other words, you should not stay in dormitory. But students who has no job, can't " I was firstly happy. Today. but last word made me low. Because I have no job. ( My high school is likely to Meister School in Germany. because my high school based on Germany meister school. But the school pressed students. Don't use smartphone and laptop in dormitory. it's like army )
