By default your parent dashboard will show the data for Mathematics, if you have a family subscription you will have access to all the other Sumdog subjects.
To change which subject data you are viewing you can click on the subject list on the left side of the dashboard. You will then be able to select which subject you would like to view.
You will also be able to select if you would like to restrict your child to a particular subject for an hour. this means that they will only be able to work on that subject and the other options will be greyed out on their child account.
