That blog post I did on Saturday was very sweet of me, that's what you get for jumping based on the first 2 chapters of the book, having read further through I say, yikes!
Yes this is really a big step up from level 1 and only in the first block of the level 2 module. As I get further along it might well be very trickly indeed.
Just remember Michael, it is a managed journey, your being taught and you, hopefully, will learn.
Level 2 study is challenging!
