I do not think there is any straightforward way to automatically regrade the
submissions after the problem is edited and republished.

This is a bit tricky because students with submissions fall under one of
four categories:

   1. Students with correct submissions graded correct.
   2. Students with incorrect submissions graded incorrect.
   3. Students with correct submissions graded incorrect.
   4. Students with incorrect submissions graded correct.

The students in categories 3 and 4 would have received incorrect feedback,
and so in any case I would draw the error to the attention of your students.

If it is still well before the due date you could assign extra tries to the
problem and tell your students to continue working on it.

Otherwise it is probably better to omit the problem from the grades
calculation (i.e., assign it 0 weight). If you manually regrade the problem
now, students in category 4 will likely argue that they could have gotten
the correct answer within the number of tries allotted if they knew their
answer was incorrect before the due date.

Hi,<br>
<br>
The students have submitted their answers to a problem with four out of eig=
ht options (four concept groups with two options each, all in one part).<br=

<br>
This problem had unfortunately an incorrect programmed answer for one of th=
e eight options. This has been corrected by the author now. Since this has =
happened _after_ the students already submitted their answers, the assigned=
 grades are not correct now.<br>

<br>
Can I now manually restart the automated grading for this specific problem?=
 I can&#39;t find any function like this on the manual grading pages.<br>
<br>
Otherwise all four options for all students have to be manually graded. We =
already figured out that &quot;only&quot; 30 students are affected. Still a=
 lot of manual work.<br>
<br>
Thanks for any hints,<br><font color=3D"#888888">
