I think we may have a similar homework disparity between standard v. Honors v. Gifted courses. I am not sure if anyone has 5 to 7 hours of homework but some kids are stressed by the workload and/or grades. There has been some instances of crying in class. My kids are pretty chill but they admitted only because they are acing everything. I am still trying to get a handle on how much homework my kids actually have. It's hard to tell because they are usually goofing off (social media, YouTube, web serials, etc.) while doing homework. There has been some late nights but only because they left them last minute.
