The bulk of stuff on ERPZ seems to have a special emphasis on Economics; in many sense it is because economics is related to so many things in the modern day life we live. Economics is evidently my favourite subject, as I wrote in my UCAS personal statement (for LSE):
"I was attracted to every discipline I was exposed to, whether it was Socrates' Moral Philosophy, Newtonian Physics and its implications on Determinism or the wonders of Quantum Tunneling. Yet Economics, with its all-pervading nature grounded upon questions of morals and justice, intertwined with the rigour of logical computations and equilibrium derivations stands out as a subject that seeks answers to the wide array of questions I have about the world." - UCAS Personal Statement, Apply 2009
I've written an Economics Essay Guide for A Level students. And Zhuoyi from Fiveless kindly allowed me to consolidate, update and abridge his comprehensive set of Economics notes, resulting in a set of 40-page H2 Economics notes that covers (almost) all the topics of the subject under A Levels.

If you prefer to have Zhuoyi's Original set of notes, I've carefully compiled the links from his site to the individual files and sorted them nicely according to the standard progression of topics.
I have also compiled an example of how one should conduct everyday reading to help one seek economics concepts in our daily lives and the things we get to learn about.
