First time.. help needed..plz

[CDM]

I'm planning to take CLEP Micro in December or January. but I have no clue where to start or how much time it's gon take.. I really need your help.

If you have a basic knowledge about the subject, how long does it take to get a good(65~75) score?
For example, I've read Principles of Microeconomics(by Mankiw) once kind of throughly. Roughly how much time do you guys think I need if i study 4~5h per day? a month? a week?

and roughly how many questions do you have to get to get 75?

Yes -- welcome to Instantcert!

I'd start with taking 1 Peterson's practice test to gauge where I was. Getting a 50% or above is a safe range to be in. Next, I'd look at the topics covered on the CLEP, and make sure that I had the basic concepts down.

Economics was one of those topics that took a while for me to "get" - and even then, I didn't really "get" it. Ha ha. Anyway -- just keep plugging away.... You'll do great!
