Teens fail courses faster with the quarter system in school. They rush to get late work in at the last minute which greatly affects their grade. The semester system is easier and more efficient for students. The students have more time to catch up on things they're missing and class lessons would be slower and not rushed.
Kids who pass thier classes with good grades are able to get more opportunities in the near future, I feel that having semesters instead of quarters is more helpful to teens in school
