Gerardo, Your grading system sounds good. We want to measure learning, and the balance between the different components is critical so as to not give more weight to a less important component, or less weight to a essential component. Although some feel giving points for professionalism merely skews grades upward, I feel this is an important category, and although different from academic measurement, it does measure conformance to specific rules and guidelines that students will need for successfulness in the workplace.
