Is it possible to report Scorm quiz results without a (formal SL) quiz?

Follow up question: I've gone through and tested a few versions of what you lay out above. What I'm currently stuck on is the following: I have 5 questions and each is worth 20 points. I would like to subtract 4 points every time someone makes an incorrect choice (each question has between 3-6 possible choices). That way, a question isn't purely wrong or right, but offers a certain amount of points. I'd like learners to experiment a bit and work through each solution.

As it is now, each question submits the full correct amount or the incorrect amount; I can't subtract one from the other once I hit "submit". Each freeform question only allows ONE final answer to go through into the results slide. I see that you've worked around this by adding buttons that are triggered for every possible choice and will report as "multiple question score", or something to that effect (I forgot the trigger name, exactly). Is there any way for me to simply subtract from the "Quiz1Score" variable? I can create variables and triggers to do some math, but I'm afraid that if I simply create a custom Score variable it won't report correctly once it's sent into the results slide and the LMS. Nothing I do seems to let me manipulate the embedded "Quiz1Score" variable, assuming that's even the variable that sends information into the LMS.
