we get a break after the hsc until uni starts.... i rekon if you want to travel that would be a good time to but i dont think you should waste a year its best to just pick up and start with whatever it is you want to do.
good luck with everything
best thing to do is to tell her that you have no up coming assessements and that you do not require her services at this point in time and that when you do you will contact her but by then she would of just forgot....problem solved
