Just out of curiosity, how much of TAOCP have you worked through in terms of exercises? I'm currently working through Concrete Mathematics and while it's a very good book, I'm also finding it very challenging, so I'm a little hesitant to even think about working through TAOCP...

I've only used TAOCP for reference. Working through it is on my to-do list, but I'm not sure when I'll get there.

The problems are ranked by difficulty, so you might be able to work your way up to the harder ones.
