Final answer:
The information provided doesn't include a specific grading policy, so it's not possible to determine exactly how much lower a course grade could be if section activities are lower than uniform grades. In general, grades are based on a combination of factors which are usually weighted differently.
Step-by-step explanation:
The question seems to be concerned with how a student's course grade may be affected by differing levels of performance in various components such as section activities versus uniform grading like tests. However, the specific details or policies regarding by how much a course grade might be lowered are not provided in the information given. Generally, a student's final grade can be influenced by a combination of factors, which often include performance in class activities, examination scores, attendance, and participation.
For example, if an equation that determines a student's GPA includes not only test scores but also class attendance and study hours, and it emphasizes that study time is weighted more heavily, then improving attendance and dedicating more hours to study would potentially have a positive impact on the GPA. Similarly, active participation in section activities could also be an important component of overall grading.
When grades are based on different components, each component typically has a predetermined weight. If section activities count less towards the final grade than uniform grades do, participating in section activities while neglecting other grading components could result in a lower overall course grade. The lowering of the grade would depend on how the instructor has weighted each component.
