If you're looking for a quick way to download your tracker view, you can simply go into your class' Live Tracking (or Year Group Overview if you need data for all classes) and click on the Tools toggle.
In the toolbar, you'll then see the option to Download. This will generate an XLS file that you can find in your download folder.
Can I download a view of grades across subjects?
If you're a Leader of a subject or a School Admin, you'll also have access to the Analysis tool, which can also be downloaded to have a file including the grades across the different subjects. To do this, you can click on Analysis from the top menu, select the relevant year group and then select Grade Boundaries. In here, you can then choose to change the source of the information in your view based on your needs.
Once you have the types of grades in your Grades Summary view that you need to download, you can click on the Tools toggle and select Download as XLS from the toolbar.
