Is there a way to set up a timer so that when the students start their test they have 45 minutes. If they leave, when they come back its still remembering how much time is left? I want to lock all the answers once the time runs out.

I don’t believe there is currently a way to do this. Here is a post about a little something I played around with that can sort of mimic a timed activity (but it would NOT stop the timer if they navigate away from the activity).

So here is the template I came up with (with a few random screens from another activity). How it works: A Canvas quiz with a time limit is created. This quiz has exactly 2 “questions”. Not really a question - just the link to the Desmos activity. A short-answer where they will enter a “complet…

I found one activity done By Kenneth Clarkson  
[Screen 3 done By Kenneth Clarkson](https://teacher.desmos.com/activitybuilder/custom/5ed7cb850138ec49f0896861?collections=63b9377ae815a5a7fdaf28b2)

I tried to adjust it alittle but I failed to change the relation between the first screen (the groups) and the screen 3 of the activity itself, but you might find it helpful

I don’t think there is currently a way to create a timed test, but you could do a combination of the following:

- Pause the activity when the test finishes
- Use the [cellEditable](https://teacher.desmos.com/computation-layer/documentation#component:table:sink:cellEditable), [disableEdit](https://teacher.desmos.com/computation-layer/documentation#component:input/expression:sink:disableEdit) and similar functions to prevent editing after students hit a Submit button

Currently, there is no way to prevent a free response from being edited, so you may wish to hide and display a copy of the response when the Submit button is pressed.
