Cool, thanks, that is useful info.
I've signed up for the BTG 60 day plan too and have been getting the emails. I haven't been following it though since I signed up for it after I had already been studying for about 2 weeks so I didn't want to start over from the beginning with the emails. After this weekend when I do my first CAT and assess my strengths and weaknesses a bit more (though I already have a good idea of where I am, at least in terms of Quant) I'll probably go back through some of the emails, esp the ones that deal with my weaknesses.
Amazing that you find "99% of the questions easy"! I find about 50% of them easy, 25% ok, and 25% killer! I'm starting to get a good idea of which quant topics I have trouble with, so I'm going to start focusing on them soon.
I've only done a few days of studying on verbal, so I have no idea where I stand there!
