Harder 3U Textbook? (1 Viewer)

[frog1944]

Hi,

I was curious if there is any textbooks (or textbook like resources) devoted solely to harder 3U? I'm aware that textbooks like Terry Lee, Fitzpatrick and Arnold have harder 3U sections, but I was curious if there was any more extensive resources (more/harder questions, more theory etc.)?

Thanks
