I can't concentrate

Hello, I'm in year 10 and I'm finding it really hard to stay focused and concentrate. I know it's not because I find the work hard, because I'm an A grade student, but in class and at home I simply cannot stay focused. I'm worried that this is affecting my grades. At home I cannot do revision and can barely do schoolwork. 30 minutes usually takes me 3 hours. Is there any ways in which I can try and overcome this?

I'm having the same issue. is there anything your got distracted by? Personally, i really get distracted by technology therefore i go to a room where there is nothing but a desk, schoolwork and me. Keep telling yourself that if you focus and revise you will get what you want.
here is something which may help you.Good luck

Thank you so much I get distracted my people and technology too, even just by music playing in the background. But when I'm at school, say in exam conditions, I somehow still find a way to get distracted and loose focus, and then end up not doing anything.
