Some good news:
-You have 2 years left in HS to prove rigor, work on standardized testing, and possibly gain some accolades for your writing.
-You are interested in environmental studies and have a unique and interesting hobby that ties into that major. I would be thinking about crafting a personal statement that speaks to this hobby.
Some bad news:
You have not YET demonstrated a strong EC story. But you have time. My D20 did not get involved in a club at school until her junior year. It ended up being very important to her and she ended up as president of the club. It played a role in her personal statement. You still have time to focus in on what you really love and make your mark. Maybe your school has an outdoors club, ski club, hiking club, recycle club, (you get the idea) where you appreciation for nature would make you a natural leader. Maybe you could start such a club.
-Midd (and all top LAC’s) are a reach for all students, even the 4.0, 1600, amazing EC students. So reach for the stars - apply away, but also make sure you find safety and target schools that are affordable and you can really get excited about.
Good Luck!!
