Listen in class and work hard on your own in order to get in the high 90's.
In physics, I would say you should do everything yourself especially the workbook exercises. In chemistry, listen to most or everything she says because it will be important in the exam and they are rarely like what you see in workbooks.
Do all the homework because that's the only way you can be prepared for her physics exams. However, if she's teaching you science or STE, i advise you to take notes in class because a lot of what she says is in the exams but not in the books.
