Moving and re-ordering problems in an assignment

To move a problem in an assignment:

1. Go to the assignment and select the Problems tab.
2. Select the drag handle (left icon) for the problem and drag it to a new position.

To re-order multiple problems at once:

1. Go to the assignment and select the Problems tab.
2. Select the Change positions button on a problem. This will put the editor into "edit points" mode.
   
3. Edit the positions of problems as you like. A higher position problem will appear after a lower one. Beyond that, the specific numbers do not matter. For example, you might set a problem position as 1000, which will move it to the end of the assignment.
4. Select Save when done.

Be sure to publish the assignment if you want the changes to be available to students.
