As the course progresses, you will be making a series of decisions in which you will increasingly specify the structure of your project. These decisions build on each other in critical ways. However, you are not locked into previous decisions if you subsequently decide you need to change direction. You have an opportunity to go back and revise and/or extend the previous section completed in the previous module. If you do revise the earlier section, please include it and indicate what changes you have made to it. Case grades given for the first four modules will be advisory rather than final
