Hereby lies the problem. You should be 2-3 A level standard to go to university. In order to qualify as a HCP.
You think that, but you are not in charge of the world.
I actually think A Levels are a crap qualification for entry to a nursing degree, BTEC Level 3 is much more realistic and involves being in a health or care setting. For a 16 year old who knows what they want to do it is a far better preparation.
Access courses are designed for mature students to get them ready for uni.
Have you ever taken an Access course OP? Have you even been inside an classroom when an Access course is being taught?
Can one normally expect to go from no/grade 2-3 GCSEs to 2-3 A level equivalence in a year?
Yes. A level is not a particularly high standard of education. I took an AS because I was not working and board, it was supposed to be distance learning. I spent 3 days studying for paper 1, 1 evening for the second paper and then I actually forgot to attend the third paper.
I still got an AS, not a brilliant grade, had I attended the third paper I would probably have got an A. That's not because I'm super smart it's because I have a level of maturity that makes it easier.
And as for your obsession with A Levels, some of us are old enough to remember S-level papers. You would sit an S level alongside your A Levels, it would not be marked unless you had an A or B in the same subject.
As for the 'one year' well most colleges teach 9-5 where as most schools teach 9-3.30, some with an early finish on a Friday.
So that's 2 hours extra a day for 32 weeks.
