I am trying to set up a problem that consists of three parts, and I am using scaffold.pl to achieve this.
I want that students work in a section at a time, and they are unable to access any other section (I want this since subsequent sections contain answers or hints to the question on previous sections). I also want to give students a unique attempt for the whole problem.
I tried by setting up the options
can_open => "first_incorrect",
is_open => "first_incorrect"
This option only allows to move to the next section as long as the previous is correct. Is there a configuration where students see the "first unanswered" instead?
I also noticed that when an answer for the current section is submitted, it counts as the whole attempt of the problem. If I set the number of attempts = 1, students are only able to submit answers for the first section.
Is it possible to deal with this issue somehow? either with the Scaffold configuration or by using other problem techniques?
