Is AIME qualification enough for a humanities major?

I want to pursue comparative lit later on in college, and I took the AMC 10 A and got a 132. Although the cutoffs aren't released yet, based on AoPS, I think I will qualify. I am currently conflicted between whether I should continue to study for the AIME, considering it is way harder and I have 7 AP classes, summer program essays, and SAT exams coming up. I don't know if it will be wise for me to devote almost 4 months to AIME when I have so much to do and I'm not a STEM major.
