Final answer:
The exact number of sections in the calculus course is not provided. Based on the question, it is likely that there are multiple topics or sections in the calculus course.
Step-by-step explanation:
The question does not provide the number of sections in the calculus course, so we cannot determine the exact number without additional information. However, based on the information given, the question states that the teacher wants to decide if handing out a topic outline before the final exam improves the exam scores of calculus. This suggests that there are multiple topics or sections in the calculus course.
