These links will take you to Khan Academy videos to help you with topics from the unit you are struggling with.
Khan Academy can be changed to most world languages. To change the language settings you do need to sign in with an account. PPS students should just use their school google account. Here is a video on how to change the language setting. Here is a list of what languages Khan Academy supports with links to each language.
