junior year schedule?

here’s my schedule for the upcoming school year:
AP US History
AP Chemistry
AP Calc AB
Biotechnology
MI
I have space for 3 more classes on my schedule. I’ve already taken English through dual enrollment, but I think I might take AP Language. I also want to fit AP Micro/Macro into my schedule, but maybe I could save that for next year.

What is “MI”?

Have you already completed the highest level of a foreign language offered at your school?

Were the English dual enrollment courses college frosh level (similar to AP English) or higher or lower level?

Do you already have three, preferably four, years of a foreign language? What type of English class did you take - almost all colleges want to see 4 years of HS English, is it a full substitute, and when did you take it?

No gym/health/required PE courses? Any arts/music/etc classes - what’s MI?
