Middle school changes, anyone

So I'm no longer living at my ex-husband's, but I am at his house three days a week so he can do cardiac therapy. Slowly digging out.

In the meantime, our older son is in 6th grade this year and I'm noticing some adjustment issues, and I thought some of you might be in the same boat.

The things I'm noticing most are: 

* issues with keeping track of things now that he has multiple teachers

* hormones  

* getting grades (instead of "Proficient," "Satisfactory," "Unsatisfactory") 

* getting grades based on actual work instead of on perceived soft skills from the teacher

Anyone else with middle school stuff?
