Just say "I haven't passed yet." Don't take it as a failure but see it as a learning opportunity. There is a lot of power in "Yet", you are telling yourself that you will get there and that your eyes and heart are still fixed on your goal.
I took the nclex exam last month. I'm very disappointed, the exam is not even close to the practice material that the prep book sells online. The level of difficulty is like 5x or 6x.
