I refer to my earlier answer...

It is true that the good students are fought over at the end of university, but recently there have been fewer places available for pre-registration training (what you have to do for a year after you leave uni) so those who have not mae an effort fall behind or can't continue.
Job prospects are good and it is a career you can be reasonably well rewarded in without having to try too hard, if that is your limited desire.
Is it hard? If you can get into the course at uni and pass it, then qualify, then you should be OK.
Would I recommend it - yes. But I wanted to do it from day one. It would not be something you could do because you didn't know what you wanted to do......
Good luck!
