I would think very carefully about this and consider all your options before making a decision - which you're obviously doing by canvassing opinion here. It's easy to get dissillusioned with a degree course, especially as we're heading rapidly towards exam time but my understanding is that you're moving into year 3 in Sept - so you're 2/3rds of the way there - might be a regret to throw it all away for the sake of one more year. One thing that would concern me is how it will look on your CV. A future employer might be inclined to look at you and say - Beauty Therapist, but didn't follow it as a career - 2 years of politics, but didn't stick at it - now wants to be nurse - this is someone who doesn't know what they want to do and will change their mind again in a year. I know that sounds harsh but you need to bear it mind. I'm 51 and studying Law after 2 different and successful careers and the biggest job I have now is justifying changes in career paths. Having said that, I think you're still young enough to get away with saying that it took you time to explore different avenues and find what it was that you really wanted to do in life. Good luck if you decide to change course. If it's what you really want to do I'm sure you'll make it work.
