Just something else to think about. Several teachers mentioned to us during conferences that if our kid needed to, they would be happy to skip homework for a night or adjust if there were several tests in a day. We hadn’t heard this Freshman year. Also, one of the teachers was in a class kid is doing great in. So, you might ask. I told my kid that sometimes things are bumpy and if you need to ask to smooth it out it’s fine. This is especially true if your kid is taking multiple AP/honors classes.
Honestly, I never would have asked when I was a student and if the teachers didn’t mention it, I don’t think my kid would ever think to ask for a reprieve. One teacher mentioned if there is a late game or something along those lines to send an email. Maybe they tell everyone this, maybe just those kids who always do the work and push through. I have no idea. I do know, the school tries really hard to adjust the work level. Even having a day off or something adjusted by quite a bit can make the difference.
Your kids faculty advisor can also give you a heads up vis-a-vis how your kid seems vs. his/her peer group. Ask them directly how your kid seems to be doing. Ours said kid was pretty stress free ( which is not how I would characterize). I would say my kid is low-medium stress. Adviser said kid is very low stress. hmm.
