I get that, for my GCSE’s and A levels I studied at home rather than at school as my school didn’t allow that, but my neighbours would always use electric tools and shout during the day, then party in their garden with loud music all night long. It really isn’t easy and I feel bad that you’re stuck in that situation. Can you invest in a pair of noise cancelling headphones? For me, they helped so much. You can reduce the noise around you, and if you want, play quiet music to help with focus.
