Hi @dev0 ,

All the test cells are frozen, restricting learners from editing. What you need to do is to run the cell by hitting “shift + return” key, or the “run” tab on the menu bar at the top of the notebook.

Every time you open a notebook, you must run all of the cells starting from the top. That’s how the assets (like the “test_your_code” module) are imported.
