Getting bad grades in Highschool

I just wanna know if I can still get into good schools with my current grades. I’m currently in 9th grade and I know my grades are really important in that year too so I’m wondering if I fucked up my resume for college apps already. In the first quarter of my first semester, I already got one B+ in math and in the second quarter I feel like I’ll get a B+ in science and a B in math (my grades haven’t been released yet). Those are the most important subjects to do well in and yet I’m doing horrible at them. I’m from a south East Asian country and I wanna get into schools in the US so I’m looking to see if getting into good schools or even possibly really good schools in the US is still possible for me. I mean I do lots of extracurriculars but I doubt it’s enough at all since I’m not outstanding.
