Breadcrumbs can serve not only as the trail of how users got to their page, but also a means for them to go back up if they chose to the parent pages, we should include links to the earlier pages.

Consider thinking about how this can scale across all pages or can you think of a way we can implement this so we can easily generate breadcrumbs on every page?

Our url path is a little weird because we do not have a dedicated page for major or career. We only have the home and results page as the parent page, so I just routed the links back to previous pages using props. Any thoughts on this?
