What are the rules with suspending study?

I am seriously thinking about doing my bachelor of ed - it's a 2 year full time degree with the qualifications I already have giving me 2 years worth of credits.

What's always made me hesitate is the fact that I desperately want to have children, and the second I find the right man it'll be happening (it can happen any time right?)... so I wouldn't want to be studying then.
But I've been thinking, why not start it and see what happens?

How does it work though, can you just suspend your course at any time? Is there a time limit to return and complete?
I have been looking at doing the same course, with same credits. I've spoken to heaps of past And present students, and it seems to be really really flexible. I'm planning to start as soon as I feel ready after baby #2's arrival, so hopefully middle of next year.

Just do it. You have nothing to lose!
