What should I do?

As a high school student, I'm really confused about my future plans. My parents want me to go to military or police academy, but what I really want to do in the future is work in science or engineering. Of course, I'm not against becoming a soldier or a cop, but I don't want to study in such a high-pressure environment. Plus, the major I want to choose doesn't guarantee that I'll find a suitable job after four years，I'm really worried right now
