when i went to nottingham on thursday a student said it is v possible if you are doing a similar course or something like that. aka if youre doing biology and want to switch to law it will be v hard however if youre doing a joint honours like french and law it would be easier to switch to law if you somehow did not enjoy the french side of the course. this being said i read somewhere it is near impossible to start a medicine course by switching because unis are not stupid and know it competitive or something idk i stopped reading at that point
hope this helps lol
