Tracking skill acquisition
I am building a course that will prepare learners to take a licensing exam. The exam covers 4 different domains of information. The course content will cover all 4 domains. There will be many multiple choice quiz questions throughout the course. Depending on which domain the quiz question pertains to, I want the answer to contribute to a total value assigned to a variable to reflect the learner's mastery of that particular domain. So I will have 4 variables, each indicating how well the learner has mastered the content for that domain.
My question is whether and how I can I have answers to MC quiz questions change the value of an existing variable?
I imagine this is a simple issue and hope someone can quickly point me in the right direction.
