Haha sorry, it just sounded funny. The first time I saw it, I read:

I agree about the proportion of time devoted to quantum. Most of the quantum on the GRE is the descriptive kind learned in general and modern physics courses which you probably already had. Only a few questions will be about more advanced formalism and theory, which should all be from the first few chapters of the Griffiths text.
Since it's only July 2, you have plenty of time to do an extensive review of all the subjects. But I suggest you start with the subjects that you struggled the most with in your practice test. Perhaps you knew nearly all of the classical and E&M problems but nearly none of the optics so you could start reviewing there. Otherwise, my best piece of advice is to keep a notebook where you write down everything you don't already know, so that you'll never lose anything you learned while studying. Also, browse this forum, which has countless discussions and advice about the PGRE.
P.S. Wouldn't it be really awesome if garden suddenly came back?
