Qnotes

[ncepps]

I have been reading previous posts on this forum and others about Qnotes. What exactly are they? Do they really help? I went to the link that another post said to try crushtheusmle.com and you can't download anymore. Also, people have said you can buy them on auction on e-bay. However, currently they aren't for sale. If someone could just tell me it is even worth continuing to look for these, I would greatly appreciate your comments.
thanks
