Should i move to the UK

Hi everyone i'm 15 and im from southern italy where the life quality is one of the lowest in europe. School doesn't work properly and i feel like i'm wasting my time every morning i go there due to the lack of any personal growth chance, networking for instance. My fav cousin's family lives in the uk and i d love to move there to study a levels next year when i ll turn 16. I hate the italian scholar system (which is based on at least 8 compulsory subjects, too many in my opinion) but i love the idea of studying just 3 a levels subjects cause im into business and economics which unluckily are not included among the italian subjects so i use to work on them on my own after school. I think my english is not so bad (im about to get B2 Cambridge certification), so if i hustle and practice during the months ahead i could make it. I dont actually know if its possible to move, and if it is what are the school requirements, but it would be a dream coming true. Any advice?
