Teddy I was told to wait one year also. Like you, I have also failed my previous final interview and I waited a year for it. I have been told it is better to wait one year because sometimes recruiters will ask you or look you up in their system and they might reject you and ask for you to come back during the later months. There were some people on this forum who said they have cheated and have gotten away with it by changing their email address on their resume, or re-applying online with a different email address.
But best of luck and wish you all the best!
Do what you think it's right I suppose, and God bless!
