Coalition Application Profile Information

Hello!

I am a prospective international student using the coalition application, but the high school information asks for my coursework all the way back to the 9th grade. As an international, my high school system is different in that it lasts from 11th to 13th grade, and for my last two years of high school, I received the IB diploma.
I was wondering if being an international student/IB graduate would change how I fill in the high school information since I haven’t been able to find any information regarding this topic.
Do I really need to find my grades from middle school?

Thanks
