While this is highly unusual, it is possible to do, especially for those students who are extending and completing a 5^th year. However, the project must a different one than the first project; i.e., it cannot be an extension of the initial project. The 2^nd project can be done in a different department, with a different mentor, etc. – but not extending the work of the initial project. If in the same content area and/or with the same mentor, the project would have to be sufficiently different in order for it to be approved for new credit.
