The university should put in place reasonable adjustments to allow the student to access the course. This might be allowing a video presentation rather than a live one for an assessment, or having a scribe for exams.
For many students, this will be sufficient.
However, for a minority, even with reasonable adjustments, they will still not be able to access the academic content of the course, or the environment in which the course is delivered, and then a conversation will need to be had about whether the student can or should continue on the course.
I would also say that there is responsibility on both sides. The student is best placed to know their own needs and should do their research to find out what their university course entails to make an informed judgement as to whether they will be able to cope with it. If they know they can't cope with group work and presentations, but willingly apply for and accept a place on a Business Studies BSc that clearly states on all its course documentation that every single assessment is group work based, then they have to bear responsibility for making a choice to put themselves in that environment.
It's like applying for a job that clearly states it is a 100% office based role and the office is in Manchester, getting the job, and then turning around and saying, I can't work in the office, I live in London, I need to work from home.
