Of course not, you’re still in high school. Did you know the average college student changes their major 3 times before deciding on what to study? It’s part of the maturation process. It’s kind of silly for a university to expect a high school student to have a list of ECs based on a future major. I would say, don’t stress over it. Keep doing what you’re doing and apply to a wide variety of reach, target, and safety schools.
