Pay attention during class and write notes about topics that you don't understand. Make sure you listen when Ms. Kim explains homework and what she expects of you because the homework tasks link very closely to the tests and what you want to be writing to get a good mark.
Always ask her questions when you don't understand something, her requirements are very high.
Do your homework. Listen to her, she doesn't tell you to do something without a reason. Unless 100% sure, NEVER argue with her
