@auvreylee Hi, you can still do Bridging. You don't actually need to have 3yrs experience to have a positive LOD from ANMAC. You will only need 3yrs if you will be needing 5points for migration purposes.
Unfortunately, you have to choose 1 among the 2 specializations and you can only claim points for whatever experience is related to that code. To get the 5points it must be 3yrs for that specific code. You can't add in your experience in a Derma clinic to that of the aged care.
