'Tis the night before quals ..
Needless to say, that didn't happen. After my thesis project switch, it took me the last month and a half to learn enough about T7 to put together a coherent proposal and do enough preliminary work to justify even having a thesis proposal meeting. [Of course, all that preliminary work was computational -- I haven't done any experimental work with T7 yet, so if the subject of experimental technique comes up, it's likely to be followed by a strained silence.]
So, I've basically spent maybe 3-4 days reviewing the 8 classes I've taken and feel like the best I can say about the vast majority of stuff covered in those classes is "Yes, I've heard of that and can, in a hand-waving sort of way, tell you about it. However, should you have questions about specifics, I will be forced to resort to the Chewbacca Defense."
In short, I feel like a dilettante. Not a good position to be in when you're about to be asked to demonstrate a "sufficient depth of knowledge across a broad set of areas", and that you're ready to start doing some [mostly] self-guided research.
