Answer: 
Yes, there is an opportunity cost if I decide to get a job after high school instead of going to college. 
Explanation: 
- Once I decide to get myself a job instead of going to college right after the schooling is over, I miss the opportunity to learn more and prepare myself for a better job than the one I would be getting after school. 
- Hence, the opportunity cost that I would be paying for deciding to get a job and not going to college would be the professional education that I would get otherwise.
