Recurring problem

My Chemistry teacher really seems to dislike me for some reason, I do very well in all assessments, contribute when I can, practically never talk during lessons and have never been rude to them, and yet they think i’m a bad student. I suspect it’s the fact that I speak rather quietly in class and kind of think for a while and carefully before I give contributions when asked but when I try and be a bit more loud then they find it a bit strange. What annoys me the most is the fact that there are two girls at the back of the class who constantly talk and yet the teacher does nothing about it and recognises their attainment more than mine and kind of views them in a more positive light than me. I’m stuck with this teacher for another year, any advice or ideas as I really want them to see my full potential and see me in a positive light but i’ve just been really confused as to why they dislike me over other students.
