I took both the tests and then did a reset for the question pool. When I retook the 1st test, I saw close to 24 questions that I was sure I had seen earlier.
Also another thing I noted was that some of the SCs and the CRs that I saw pretty late in the 2nd test came right upfront in the retest. Really not sure what to make of it.
Now with 2 weeks to go, I am thinking of buying the new exam pack1 coz GMAT prep is virtually useless for me in terms of getting a realistic picture.
Take care to get what you like or you will be forced to like what you get!!
