how do i find out what score i need to actually make? from my school? Does the score that appears on the screen once you have completed the test tell you anything at all about whether you passed or not? i'm so nervous.

Has anyone used only instantcert and passed comfortably? As far as this exam goes(Macroeconomics) is it wise to use another study guide as well? Also is the macro exam relatively easy or difficult,as I've read some people post about accounting? Thanx!!!
