CustomCollegePlan (the student account) works on both desktop and mobile. For that reason, the interface is slightly different depending on how the student is accessing their account.
Desktop device (such as a laptop computer)
To-Dos can be found within a tab in the left-hand navigation called To-Dos. To-Dos are shown in a kanban board format. Students can drag and drop the To-Do items from one column (status) to another. Clicking on any To-Do item allows the student to see more detail, add comments, and change the status.
Mobile device (such as a phone or tablet)
On mobile, students tap the hamburger menu in the upper left-hand corner, and select To-Dos from the menu options. Tapping on a To-Do Item will expand it to show more details, comments, etc.
Instead of dragging and dropping (which is hard to do on mobile), students can tap the "flip" icon on a given To-Do item to see options for changing its status.
