If you need to apply for a student visa, please check the UK government website before making your visa application.
We accept high school leaving qualifications from every province and territory. Typically the minimum requirement is 5 or 6 subjects from grade 12 or CEGEP at B or better, or 80% average (dependent on grading system), including pre-requisite subjects in some instances. Certain courses require a higher standard, for example the 3 year Law LLB requires an average of 85%.
If you are coming to the UK to study a course that lasts longer than six months, you are likely to need a Student visa. You will be able to apply for this after you receive your CAS.
