Thanks for the reply. But I'm would like to make sure that student visa is the Type I should apply for my exam visiting. As my situation is not fit any of the criterias on the website. I've got my veterinary degree in China already in 2008. The exam in UK actually is not part of my veterinary study. It is more like an assessment to prove I'm competent to work in UK as a Veterinary surgeon. So could you please help me to double check that whether a student visa type is the right one? Thanks again.
