I'm not a SAHM yet, but I'm currently back at uni. As for the juggling of the finances, this semester I'm paying for my subjects via direct debit (fortnightly payments - subjects to be paid for before exam week), but I've put the forms in for "fee help" which is basically HECS (your student loan type thing that you pay off once you earn a certain wage), when the paying via direct debit for the subjects gets too much (currently $450 a fortnight) I'll swap to the fee help (which I will start paying back straight away because of the money I earn).

As for the studying, in the past I found it better if I just headed to the library for an hour or so after a lecture/tute (unless it finished at 9pm!) to re-write my notes and do a bit of study. I also used to schedule in my study time, you'll probably need to look at daycare options, for when you're at uni and for probably a day a week when you need to study.

When I fall pregnant, it is going to be interesting juggling uni and pregnancy as I have lab hours and some of the stuff we work with is harmful during pregnancy, am trying to get those subjects over and done with as soon as possible or will be putting them off until after bub is born.

Good luck with it all.
