I think it will definitely have an impact - I don't think it will be a massive change, and medical school places will remain very oversubscribed, but there has already been a bit of a drop in applications in the last two years, and I'm certain that in this climate, the general trend will continue.
Applications-
2013: 17,000
2014: 17,140
2015: 15,220
2016: 14,820
Numbers of EU and international applications haven't fallen though.
Ploughing ahead with university applications without taking job conditions into account just doesn't make sense to me. You might not have a crystal ball and you can only look at current conditions and trends, but to make a informed decision about your future job, you need to base it on information which includes money, hours etc, as well as your time in your local care home. Basic common sense, right?
It'd be great if the way life worked was 'if you have the "right attitude" and the determination, you (and everyone else) can and should be happy to do anything, just push through and it'll work itself out' but it doesn't. We're only human.
