I made to Chapter 21! Yeah! These last 2 chapters have been the most challenging so far. All in all I'd say that learning this theory has been easy for the most part.
It is so well written and has clear cut instructions making learning a breeze.
Don't get me wrong, it's very hard work. But if it's fair to say that this work is fun then that's what I have to say. I am really enjoying it.
I peeked ahead to the next chapter and it's all about numbers. I look forward to the next challenge.
