We just pushed out a minor update for GradeWizard. This update addresses the bug where the sample data is inserted multiple times. We have also added the much-requested ability to delete grades. You can delete a grade easily by clicking the grade and then making a blank entry into the Enter Grade field.
Also, new terms are now added to the top of the term list so it functions as a “Most Recent” ordered list. It should be noted that this is actually just a temporary fix while we continue to work on the real solution to the ordering issue, which is allowing the user to completely reorder terms, classes, grade groups, and grading schemes. We are hoping to have that feature ready for our next release.
