Description:
The mark/unmark feature lass diagrams in the Developer Guide are using non-standard notation that doesn’t align with the conventions covered in the course. Specifically:
Attributes are shown with squares in front of them, and operations are marked with circles
The return type for methods is in the wrong order.

From course website:

Suggested Improvement:
- Update the diagrams to remove the non-standard symbols in front of attributes and operations.
- Correct the placement of return types to match the format covered in course materials.
