No you'll have the same classes as Uk students. There were many international students while I was at uni, I just finished uni. They all had the same classes and coursework etc as me and other uk students but some had to take English lessons because they weren't fluent in English and all coursework obviously has to be done in English and is the uk language which tutors will speak. College qualifications are obviously different around the world. What did you study at college? Your college qualifications should be accepted in the uk. Look at the uk websites of the uni's you want to apply to and see what the requirements are for international applicants for the course you want to study. It should tell you the qualifications they accept from international applicants.
