I have passed FCE two years ago and I think that if you start doing the C1 mock exams you could get it easily, C1 is more about vocabulary and fluency so you'll pass it for sure with your year abroad experience
Bear in mind that all these exams are "perishable". That is, they have an expiration date, so your hard-earned circa 200 euros will be spent on something that won't last but a couple of years (and won't even be recognised in most English-speaking countries).

I had my b2 with a high mark btw por que cojones hablas en inglés en un foro español?

Palomos somos todos pero sin duda tu prima la que mas.
My advice: I am an English teacher and whether my students are used to hearing English in class or not, it is the language I always speak, although I grade my language all the time tailoring it to their level so that they can understand me, but they like me because I am myself a challenge for them. Do not rely on those who promise you they will be able to make you pass the C1 exam in a week as that means, in broad terms, a bullshit on the road waiting for your blindness to stumble into it and get psychologically frustrated because of their fake promises. Rely on yourself and practice as much English as you can. If I were you, I would not think twice.
