Go to My items > My classes or click My classes in your Favourite links section.
On the My Classes page, you will see all your classes and the linked assessments that have been created in Arbor. You can see any courses, registration forms or teaching groups you've been linked to.
For Primary schools, it's likely you'll only have Registration Forms as your classes.
When you click Full Marksheet, you'll be able to see a marksheet with all Summative assessments linked to the Registration Form.
When you click the All Assessments option, if you have multiple assessments linked to the registration form you can select a specific Summative assessment marksheet or Curriculum assessment markbook to access from here.
For Secondary schools, you'll likely have courses as your classes.
For courses, it's likely there will only be one assessment linked to each course, so there will only be one assessment showing in the marksheet when you click Full Marksheet.
When you click the All Assessments option, if you have multiple assessments linked to the course you can select a specific assessment marksheet to access from here.
It's unlikely you'll be assigned a Teaching Group as one of your classes. If you have been, you'll see you're only able to select All Assessments, and chose a Summative Marksheet.
