Ok so do you have GCSE maths, english and IT C and above?
If not, you will need to do the equvilant course. Then you will need your A level, this can be done at most colleges it is called an access to higher education course.
That will take you a year, then apply to uni and do a nursing course.where you will need to do placements i think you are in uni two days a week the rest on placements in hospitals doing nights, days, working doing a wide range of caring.
It will be hard going, so do make sure you are right for this type of work. My friends have done it and if they didn't love their job they would cry at somethings they have had to do.
Also uni places are limited, so if you go in and say you want to do botox you will not get a place.
Also take a uni open day and go and speak with the nursing team, and the finance team and see approx what uni would cost you in student loans, and what is expected of you on the course.
Good luck
