I have a question concerning the calculation of the scores. I understand that it is not really the amount of questons you get right, but it is the diffculty of the questions you are getting. Is that right? So, if at the end of the test, i am getting questions in the 600-700 range, and i get those right, can i assume that i would get a score between 600 and 700? I just want to get a better understanding of the test scores. Thanks.
