It's not difficult, if you are serious. Homework, if your teacher is merciful, homework should be finished at school, if the teacher is cruel … it's hard to say. Just like the usual homework and exams, there will be several answers to some questions in the later chapters, so we should think seriously and think from multiple angles. Usually I am very serious in class. Generally speaking, classes below level 7 are not difficult. Ask questions if you don't know. If you think about it yourself.

Believe in yourself, you can do it!
