What should I do after getting rejected from my top university?

I've tried really hard on school this year and have a 91 average but it's not enough... I just got rejected from my top choice business program today and I don't know what to do now. I've only got accepted into 3 programs but they were all backups and the more I think about it, it's not what I really want to do. Should I do grade13? Or just go to another program? But also I've never wanted to do grade 13, and I don't wanna be like one year behind everyone if I do go to university after that...

What should I do now?
