Hi

You are going to need three serious qualifications, including chemistry and biology, from your last years at high school

You should have some early experience of looking after people in a social or medical setting, perhaps in a voluntary job

You then do four or more years of hard study, maybe a couple more in the area that you want to specialise in. This will include long hours of work-on-the-job, as you train

Those are the sorts of things that you need to be able to do
