Do you actually want to work as a nurse on graduation? If not then it may be best to look at other courses - the placements are probably just going to get harder and more draining as the course goes on, especially if you have no interest in doing that work anyway.
That said, do consider carefully the financial implications of it. If you're in your second year, you won't have full SFE funding for swapping to first year of a new full-time degree.
