I've just tried changing the assigned score values from fractions to decimals
and this gives the same results.
As another data point, a score of 12/15 in the puzzle with an assigned_score of
.8000 comes out as 4.85714285714285 points out of 5 in the course. I am
expecting that to be 4 out of 5.

Subject: assigned_score and unexpected results
Hi All,
I have a word search activity implemented in Lon-Capa worth 5 course points if
completed with no hints. There are 12 words to find plus 3 "starter points"
that you can spend on 3 different hints for a total of 15 possible points. In
the course parameters I've weighted the activity to 5 points. In the activity
itself I've used assigned_score as follows:
if($submission eq "12|3"){return (ASSIGNED_SCORE,15/15)}; #12|3 means all words
found and no hints used, etc.
if($submission eq "12|2"){return (ASSIGNED_SCORE,14/15)};
if($submission eq "12|1"){return (ASSIGNED_SCORE,13/15)};
if($submission eq "12|0"){return (ASSIGNED_SCORE,12/15)};
My expectation then, for example, is that if I complete the puzzle using two
hints, in the course I should see 4.333 points awarded. However, what I'm
seeing in the course for that outcome is a score of 4.90476190476191 out of 5.
The Word Search problem itself is a one-part problem with 7 customresponses;
however, the score should be coming from only the customresponse with the
assigned_score section shown above. All of the other 6 customresponses are
weighted at 0.
So what am I missing? Thanks!
