PLEASE READ CAREFULLY!
We just received an alert that Bb has confirmed that having " no-print code" within the HTML (<>) within Bb will cause the testing feature to be flaky. The example provided was that an instructor put the "no-print code" on a test, and after student took the test, Bb wouldn't allow grading and it wouldn't auto-grade either (it was multiple choice & essay). After an extensive investigation, they determined it was the "no print code", removed the offending code, and the test functioned correctly.
Please share this with everyone! Also, please let them know that any tests that get copied from one course to another with this code, or any courses that get copied or exported/imported with tests with this code will have the same issues.
