Answer:
B. take classes in high school that will give her college credit.
Explanation:
This is one of the ways in which Sheila might be able to attend college. By taking some classes in high school that will give her college credit, Sheila would most likely lessen the load of classes that she has to take in college. This will allow her to take less classes in college each year, reducing the fees she pays. Otherwise, she could also choose to take more classes each year, but stay in school for less time. Either way, her tuition costs are likely to be lower.
