Help me get a proper study method

I study by reading it for 2 to 5 times. Say the lines without seeing book and try to perfect. I continue it with the entire paragraph. Next I write it in my copy.

I tried to do Active Recall. But I didn't know how to do it. I just revised everything like the top paragraph you can see. So it took long hours( shorter than doing it first time tho). I don't this with everuting: History , Geography, Bio, Physics, Chemical Formulae and Chemistry. Except maths obviously I practise it 3 times a week. I cannot improve with this and slowly became a bad student. I think I have low IQ because I forget it 1 week later easily. I have no friends . I ask the topper. He keeps it secret. I also have no proper schedule . I have like 6 tuitions. My school is a pretty reputed school.I heard most toppers get good by following our class schedule to study after returning. Please, I trust the Internet here. I'm an 8th grade student😞
