To nauadpi: I'm soo jealous!
I wish my viva (our equivalent of the defense) was that soon! I just submitted my doctoral thesis on Friday (in its 400-page glory) and have yet to hear when I will be viva'd. Is it standard in your programme to have such a quick turnaround between submitting and defending? I may have to wait anywhere from 4 weeks to 3 months (the maximum time the examiners can take to read the thesis). Hopefully it's sooner rather than later...
Best of luck!!
