<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">I am getting an error I don’t remember seeing before with a formula response problem that takes a Greek letter as part of the formula. The odd thing is that it works fine for me, whether in student or course
coordinator mode, but not for the students. I have been able to recreate the error by logging in as a student to a Test course and doing the problem from there. The first time I submitted a response it took 20-30 seconds to process, and gave a timeout error.
Subsequent submissions appear to process much faster, and gave an “Unable to understand formula” error. It is set up to take either of two formulas for the answer.<o:p></o:p></span></p>
