why are you even on a pathway plan?
sorry, you have a 1 year old don't you? and a four year old?
what payment are you on? is your partner on parenting payment cos if he isn't, you should be!!
i would be querying an exemption to compulsory activity based on being principle carer of so many kidlets (providing your DH isn't on the parenting payment)

IF you are on newstart due to your partner being on parenting payment
it's a GOOD thing she put your course into your pathway plan. if she didn't take that into account (as you are doing it on your own back) your expectations to c'link would be higher than they are at the moment, PLUS you would still be voluntarily carrying out your studies kwim?
