Hi Mummabear,
Good luck with the study. As for me, I probably would have given that advice anyway! I have studied my own degree full time while working full time, and did some part time study whilst on ML. Now I am back at work part time and am going to do 2 units first sem and 1 unit second sem to finish my second degree...

...then! I will do my MBA the following year.

If I get a BFP somewhere in amongst all that, then bring it on. You can always defer, drop a unit, apply for extended leave, etc etc. Uni is so flexible that there is always a way if you're motivated, which sounds like you are.

I am from the "suck it and see" school of thought or from the "glutton for punishment" school of thought, depending on who you ask.

Good luck again,
