Sum total overall score

I am testing some courses in Sum total 7.2. I have tested a single SCO course and the behavior is correct but when we tested it with a course consisting of 2 lessons and 1 quizz I have seen that the total score is calculated as the average score for all SCOs, for exampl (See attached image)

I wonder if there is any way to assign weights to different SCOs (0 for lessons 1 for evaluation) or if the only way to solve this problem is to use courses with a single SCO that contains lessons and quizzes inside (sending cmi.core.score.raw from the test result) or separate lessons in one course and test in another one.
