Help with UCAS Education Section + What are my chances?

Yellow just pinging you once again for help because you’ve been so great so far!

Quick question: should my school counselor or a teacher knowledgeable with PPE be writing my reference? I get the sense it should be a bit of both but I’m unsure.

I elaborate more on this in my latest post if you wouldn’t mind reading that it will explain my situation a little better. Thank you if you can reply! If not, still thank you for the help!
