Should I go to Swedish University

Im born in Sweden and have a Swedish passport , so i believe i am eligible for the free tutition of any Swedish university. Ive studied my whole life ( year 1 - 13 ) in England. Thinking about studying in Sweden for univeristy and would like to know what people think. My current plan is to study there and if i dont like it then come back to London! I may take a gap year as im currently mid-way through Year 13 and have not decided. If it all sounds messy, its becuase it probably is.

Few things to know to aid your judgement: 1. I do not speak Swedish currently but alot of family live there and can help

  1. ALOT of family live there so plenty of accomodations

3.I do like my social circle in London (i know it will not sway my decision massively but i have a girlfriend here too, but its healthy so distance may be okay - but thats not too relevant)

4.I currrently want to study Psychology but may move into polysci or politics

Hope someone in the world is also in my position. And help is welcomed and appriciated.
