The booklet in question is about 30 odd pages now, it was smaller when I went through the application process although that was 14 years ago now. That said, it's very easy to learn it, if you really want to.
Crazy Voyager has it right with the rest of it though, you will get absolutely bombarded with things to learn in the first few weeks and if you're concerned about your ability to learn a few basic facts from the booklet then you will struggle.
