# [LON-CAPA-users] assigned_score and unexpected results

```Thanks Stuart. I knew I was missing something. I thought that the weight parameter could be applied to individual responses like sig fig and tolerance parameters can. However,
understanding what’s happening I think I can work things out to the outcome I’m looking for.

OR the other 6 responses are also all customresponses. If I used assign_score in each of those responses to give a score of zero, would the Lon-Capa assume the answers are incorrect?

(The other answers are just storing data to restore the puzzle when the page reloads, so are set up to always be correct.)

Thanks as always!

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:
