One of my recommenders teaches computer sciences, do I list her as a teacher in Science or Other on the CommonApp?
I don’t think there is a definite answer, and therefore I don’t think it will matter what you list it as. Some people even consider computer science to be math. The label isn’t important in the grand scheme of things, admissions officers care about what is written in the letter.
If you have 2+ recommenders, most college advice says that you should have one recommendation from a humanities teachers and one from a math/science teacher. So, if you already have a math or science recommendation, list it as other. If you don’t have a math or science recommendation, list it as science.
