Seeking Feedback about Berkeley High Math

I'm interested in hearing about other families' experiences with the Integrated Math (IM) pathway at Berkeley High School (BHS), both the regular and Honors tracks. I have a few specific questions:

1. Did you feel that BUSD middle school math (or private school) provided solid preparation for the IM sequence at BHS?

2. If your child consistently received 4's in math during elementary and middle school, did they find the IM Honors track accessible and manageable?

3. Was there a particular level in the IM sequence where your child began to feel overwhelmed, or has it been smooth sailing throughout?

I would love to hear any insights about how your child has navigated the IM pathway and advice about ways to make sure your child thrives in it. Thank you!
