Hi Gene
Thank you for the quick response and the good idea.
I implemented it in a way that is demonstrated by the enclosed minimal example.
(The use of 'ASSIGNED_SCORE' I grabbed from the author guide page 48.)
Is this the way to go?
And a follow-up question --
To confirm the assignment of the score do I have to publish the problem and
import it into a course?
Or, is there a way to show it in author space?
Thanks!
Itay
Minimal example follows:
<problem>
<startouttext />
Write down a solution to the quadratic equation <algebra>x^2 + 2x + 3 =
0</algebra>. <br />
Write the string 'NA' in case there is no solution.
<endouttext />
<customresponse id="11">
<answer type="loncapa/perl">
if ($submission =~ /^\s*NA\s*$/) { return('ASSIGNED_SCORE', 150); }
# Here, in a full problem, would go code that handles the other cases.
return 'INCORRECT';
</answer>
<textline readonly="no" />
</customresponse>
</problem>
