I need to study the book Principles of economics (Mankiw), I've got 4 days for the 800 pages. By reading the book, I'm only doing 10-15p/hour. There are a lot of examples, repetitions,... in the book so I'm actually looking for a summary or something which is complete, it can still be about 300p it's OK. If anyone had to study it, give me some advice please 
. Thanks a lot.
