The tests and participation literally make or break your grade. Homework section doesn't give you anything. Do well on the tests and make sure that when she passes them back, she adds up your points properly. Also, if you raise your hand literally 10 times a day she will still give you a B in participation so just know that.
Memorize everything and participate as much as possible because that's 20% of your overall grade and even if you think you participate enough, do more.
