[Leanne101]

Hi I would just like to know what i should do right now because i feel like i will have to repeat my leaving cert this year . I Dont think i did good in the leaving cert 2010 . I don't want to repeat all my subjects as i feel like i did good in some of them . can you please tell me what i should do . I would also like to know is there a fee for repeating not all but a few subjects. can you also tell me if i can still change my cao ?? or can you not anymore?? Thank you !
