Try revising outside of home - home is the place you relax so it’s hard to focus on schoolwork when all you wanna do is nothing! Try different places, maybe in the school after lessons, a local library, or a coffee shop. I can’t do work at home but when I go to a coffee shop to write my essays the attempt to make it “aesthetic” is the biggest motivation for me lol. Revising subjects with friends who also take them is good too!
