Hi,
Thanks for answers.
I think that it is possible to determine weight (amount of points) of each question...
I understand that GRE CAT works in this way:
let say you have answered first 5 questions correctly. your current score is hmm.. let say 650. If you answer next question correctly the score will be 650 + x, if incorrectly, then 650 - x. So x is the weigth of sixth question.
I think that this doesn't vary from test to test.
If I am right then one way to determine weights is to take gre powerprep test several times, and try for given X = 5,6,7, whatever, to answer
first X questions correctly, rest incorrectly
first X questions incorrectly, and rest correctly
This is tedious and time consuming, but if we know how many point is each question worth, then we can determine how important last five (or other number) questions are.
If for example answering last 5 questions incorrectly is going to lower your score by only 20-30 points, then we can ignore them and spend more time on first 25...
Any comments on this?
