Right you have to really think this one through, i am not advising you do this.
I am a qualified nurse, now when I got into University I met two people with criminal records... How did they get on the course they didn't tell the university they had a criminal record... The ducked and dived the CRB process one managed this until 3rd year and they allowed him to stay on the course after because he had proved his trust, he was charged with GBH. The other dangerous driving, was allowed to stay on.
During my course 2 students got done for drunk driving, one even toppled his car on the motorway drunk both still qaulified.
My friend got caught with Cannabis possession when she was like 16, didn't declare got accepted for an art therapy degree now work is in a school.
Where does honesty always get you? You have to behonest as a nurse, but for you maybe you have to reflect on the examples I've given you.
if I was an admission tutor and I knew you had a criminal record I would say no because I have 1500 other applicants who don't. Now it's likely this will get bought to you in the first year as sometimes they won't let you do placement, then beg and plead at that point saying as you are how desperate you were but nobody would consider you
