Change your preferences for the late and final rounds for something with a cut-off you know you can meet (like Arts or something). Then do that for a year, do really well and apply to the course you really want to do next year. I know that's not an ideal situation but it's better than not doing anything at all
If you are going to make a thread like this please either make a question so that people can help you, or write it like a story, sharing the background and events that led you up to this point, so people can sympathise with you.
I'd feel for you if I knew what happened, but I don't know, so I don't.
