yeah its not all that good...
95% of it is these massive set of excercises which might be good if u did them, but look like they take so f'in long i doubt anyone has ever done them. It does have a few decent summaries... like the one for people and economic activity it provides a good 1-page run down. Its hard for geography though because you're going to be using your own case studies anyway, and not something out of an excell. As for the skills sections i'd say its pretty mediocre. Some of the practice essay questions are worthwhile but some are a bit out there.
I don't like the geography text-books either. Its all so vague. It seems to me that for geography you can talk about a huge range of things to give a decent answer that may or may not relate a great deal to the question.
for example in half the study guides and things it has say "Nature, character and spatial distribution of megacities" a nice big title, and u think sweet, something straight out of the syllabus i have to know. THen they just BS on about how blah population increase blah rural urban migration etc and they don't say a thing about the actually nature or characteristics!
OK enough extended response rant on geography.
