how often is gmat prep software updated

If you download the software now after one month, you will find new questions but there will be repeats and most importantly you will have an inflated score(Because of those repeat questions!)

Can someone tell me weather the two official practice tests each have a different pool of questions?
And if not so, why would the questions not repeat in second test?

As much as I know , there are 2 diff pools for the tests. You will don't find overlap between the 2 tests

Is the second test tougher than the first one?

Both tests are just as difficult/easy as the actual test

As far as i understand.....there should be just 2 sets of GMATPrep softwares....
I believe that just two sets of binaries which have been released by mba.com till date,
I have seen only two .exe files with different size on disk over the last two years.

However apart from the analysis of the filesize(cksum)

right click--> properties-->version number gives a different story.

File version: 10.0.0.159 for size 26,745,607 bytes

File version: 10.0.0.162 for size 27,142,744 bytes

but if somebody sees an executable file with either of the two sizes,but with different file version number,
it should essentially mean, that the content remains the same and its just that its been repackaged.

Many people have claimed that a new download gives them a set of new questions, but uninstalling and then installing again the same executable also gives new questions. This happens I guess because the questions database of the two tests might be BIG.
