Because the UCWISE system is under constant development, versions of the system used in previous semesters are generally not compatible with the current version. In order to see student work in these previous semester, we have taken "snapshots" of the database and code and provided links to these snapshots.
If you were a student in a previous semester, your account should still be active in the snapshot. You could send a trouble ticket to the UCWISE staff if you have forgotten your password.
