Review on AS Economics Unit F581 MArkets in Action!

After I read through all the papers which is up to about more than 90 pages, I found some good things about the book and some bad examples about the book.
First of all, it explains things such as definitions of the economic terms and examples to support the idea. For example, when it is talking about scarcity, it gives definitions as "Human wants are practically unlimited but resources available to satisfy these wants are limited or scarce. This creates the concept of scarcity, which is known as the economic problem." And it also shows many different forms of scarcity such as; time, resources, information, and consumable goods. I think it is not a bad definition and it also gives some related forms of scarcity, so, so far it is good. But from here they just finish talking about scarcity and just go over to the next topic. I believe that they can talk about the result or consequences of having scarce resource such as that individuals and firms have to make choices due to scarce resources.
This was just an example of one topic, but the point is that for the all other subjects it does same things; definition and little bit of examples. Furthermore, I think if it is review papers, then I dont think that they have to contain so much exercise as this review sheet. In this review paper, I believe about half of the 90 pages are exercise questions, I think it is better to write more details with well- explained and well-organized sentences.
Lastly, this review sheet has problem with organizing topics in order. For example, it talks about some topic and then even though the writer could have written everything related to that topic at one page, but he writes some part in the beginning and some parts at the end which makes so much complication for people who are not good enough or who do not have enough knowledge to understand those complicity.
Oh,yeah, one more thing, it doesnt have that many of answers or diagrams for exercises given, so if someone does not know the answers, then they will be stuck so deeply. Apart from this, I liked this review sheet.

Thanks very much!
