Captivate 9 Knowledge Check Decrement score

[simonb27458783]

I am using Captivate 9 and have two knowledge checks in a module. I'm using knowledge checks (KC) so that the scores are not recorded to the LMS and so I can have two separate sets of questions in the module. A score will be kept and displayed at the end of each KC though.

I would like the KC to work such that you get 2 attempts at each question (5 questions), a correct answer gets 2 points but an incorrect answers gets -1 point.

I've set up a variable for each KC, score_1 and score_2. I've set up a script so that neither score can go above 10 and below 0. I can get the scores to increment by 2 points and have 2 attempts at each question but I can't get the scores to decrement by 1 on an incorrect answer.

Is there any way of doing this in a knowledge check please? Thanks.

Can you post a screenshot of the advanced action or shared action that you use?

Is this what you mean?

I thought you were calculating a score, but you just show me a Properties panel? You don't know anything about advanced actions? You'll have to create an advanced action for the Last attempt, where you use the Expression command to subtract 1 point from the total score. If the total score is stored in a user variable v_total, that  action 'FailureAct' would be something like this:

     Expression v_total = v_total - 1

     Continue

However there is one big problem: Captivate cannot manage negative points. This means that the score will remain at 0 if the first answer is a failure. You'll have to tweak this: you could start with a default value for the variable v_total of 5 points, and at the end create another advanced action that subtracts 5 from the score to restore the correct score. Even then you'll have to be aware that this total score can never be below 0.
