Changing school..? 10 points ;)?

Kk im living in england as i was born here lol so was my mum (she isnt english though) so im at secondary school and in year 8. my mum and dad are offering me to live for bout a year in my dads country for school there... I dont know what to do?! Its a really hard decision as it would change my education, I want to go see my family and have a better education but its gonna be hard for me to leave. Im really stuck my dad said he will ring me later to talk bout it. My friend is leaving school soon so i dont mind leaving but i will miss my pets, family and crush... I know i sound greedy but i feel like i dont know what to do... So what do you think i should do and what you would do. I dont understand the language fluently and its in europe. Thx questions are: what would you do if you had this choice? And what do you think i should do? :D
