question for PME PRIMARY Students / Teachers.

I am a fully qualified Psychiatric Nurse looking for a career change. I am thinking of doing the PME Primary teaching. I only have O4 in Leaving Cert Irish. Is it advisable to just do the B2 exam (My Irish is so poor at the moment), Or leaving Certificate Irish next year (Which I am already confused about because if I done the LC Irish in 2027, the deadline for all PME's is April so my results wouldn't be back) Really confused on what to do or If i done the PGCE Primary in the UK, and my LC Irish the same year, could I transfer this degree? Any help at all would be appreciated. If I could start in September I would but it's the Irish that's letting me down big time!
