ACT struggles?

I know most good universities want really high ACT scores. It would be my dream to get a 30. However, my school does practice ACT tests and when I took it as a freshman in high school last year, I got a 22. I know that score is horrible. There’s no way I could get into a good or even decent college with that score. And what’s frustrating is that I’m a very good student. I’m taking four honors classes and one AP class. Next year I’m taking 3 AP and 2 honors, and I usually manage a 3.8 or 3.9 GPA easily. I’m in 3 extracurricular activities and I volunteer outside of school. I’m also of south asian descent (I heard having a minority background is good for college?) Anyway, how can I bring my ACT score up? I know I’m not stupid. I think I’m just a horrible test-taker. How much could my ACT go up from freshman year to the middle of Junior year?
