I've tested it: You seem to suffer by the same strange maxima-bug on host 'mtal1', see the 'catching maxima errors'-threads on http://mail.lon-capa.org/pipermail/lon-capa-users/2012-November The problem is still unsolved. Therefore you have to check *all* syntax errors. This was the initial motivation for my library-project. Maybe I can offer a preliminary workaround-library ... Or can someone finds similarities of the hosts 'mtal1' and 'scll1' that may cause this bug :-/ ? - Peter Am 21.10.2013 16:23, schrieb Angus Findlay: > When I give students formula response questions some of them don’t submit > valid mathematic expressions.
