Hi Everyone

First I am so amazed about how much information there is on this forum.

I have a question and would like to hear some advice and what others think

How much should one spend on materials and books for Exam preparation.

I did a search on Macro and Micro Economics and I found different suggestions and books, by the time I was finished I had already book about 3 book from Amazon costing me about $40 totals.

How much is to much or too little; money wise and material wise

You input will be highly appreciated
