Where can i repeat the leaving cert?

I did my leaving cert in 2008 didn't do very well at all only 170 points wasn't bothered at the time as i had planned to do a PLC but failed that. I wasn't really focused at the time but now i would love the chance to go back and repeat as i found a career that i would like to do. Is there any other options on how to repeat without going back to secondary school?
