Just my 2 cents. Being the Val or Sal is a nice honor, but you’re right, it’s often the kids who work the system to their advantage to end up there. Is that title important to you? Because if so, then you can make those same choices and maybe be the Val too. But, if what you’re learning is more important than that honor, then continue on the path you’re on and be proud of your decision. My daughter made a decision early on in high school that she was not going to get wrapped up on the race to be the Val. Would she have liked the distinction? Yes. But not enough to choose all her classes in order to reach that goal. She graduated ranked high, but not the highest in her class, and took the classes that she felt would best help her reach her goals. That’s not to say there is anything wrong with those who find that distinction important. It’s just not something that is important to everyone.
As for others getting recognition that you wish you were getting: Welcome to life. It happens all the time. But you should strive to do well because YOU want to do well. Not because you want a pat on the back for it. I know it’s frustrating, but those who matter will notice your accomplishments, even if they don’t say anything about it. My daughter was also overlooked when the “loud” kids instead got all the attention. We used to joke about it at home. But you know what? She is now a freshman at a college she loves and no longer cares about what some random teacher or high school classmate did or did not say to her.
My advice to you is to spend some time thinking about where you want to go in life and focus your energies on achieving those goals. Is college a goal? Are there particular schools you want to go to? If so, focus on the classes, grades, and activities that will help you build a good application and ignore all the rest. You can represent your country well by becoming a success in the future. I would not worry so much about high school.
And finally, remember you are dealing with a different school system. To be successful in the US you are going to have to figure out how to be successful in our system. Trying to match what is happening at home seems futile.
