For this chapter you will get to choose between doing most of your exercises on your iPad or in your notebook.

- If you work in your notebook, you can follow the studyplanner for your chosen path (support, standard or challenge). Check your answers with the solutions book, if you get an answer wrong, try answering the question again.

- If you work on the iPad, I will keep track of the time you spend on your exercises and how well you did on them. Some exercises (such as drawing graphs) you will have to write in your notebook. Your answers will be checked for you. If you get an answer wrong, try answering the question again.
