we all miss things for various reasons, unfortunately in school we dont have the time to recap everything.
To find missing work:
Log onto your Google Classroom
Find the topic you are studying
You should have done every titles in that unit
If a title is new to you - you probably missed it.
Open the lesson and complete the work set!
you can use the links on the lesson, the PowerPoints, your knowledge organisers anything you need to answer the objectives.
