Hi vikramm
I have downloaded some of the paper tests and I find them quite useful.
Some portions of the pptest are from the 10th edition but it's always good to have some more practice questions.
Obviously, the paper tests were taken in a different form.
The test consist of 5-6 section. :There're 2 ps, 1 ds, 1 rc, 1 sc and 1 cr.
So, you have to take the paper tests in the way that they were taken, which means that you won't get the CAT experience but on the other hand, it's always good to get some more practice and these questions are ETS questions, real question. The scores that you get from these tests also shows you where you are or in which level you are at the moment.
Cheers,
