Study / Credit Transfer from China to Poland (Warsaw University of Technology WUT?) [2]

Hello there,
I am trying to apply for Warsaw University of technolgy, I have finished IGSCE O levels with English also, and could not finish A levels for some reason, I saw Warsaw University have a foundation course, and the deadline is around january-february, even if I apply I might miss some days or even a month because of facing embassy etc. So I for now if could not get a chance in the university, I can go to university In china with full scholarship, and after studying there for a a semester I wanted to credit transfer from china to Warsaw Poland. Is this possible? And another question I have is that do I need IELTS english for poland? Or will my IGSCE O level English will do the job. Please help me someone, I am in a big mess :(
