You are right.They have never been the same, at least for the last 10 years. I don't think there is any reason to delete the discussion of the test questions for that. It would be very naive for the CB to repeat the same questions from a test that was administered a couple of days before and both of them will be public in a couple of months
The test has NEVER been the same on Wednesday and Saturday for obvious reasons. There is no reason to delete the threads. They will never use these questions again since it is a released test that all students can get back with their score report.
And CB is way too smart to use a test on Wednesday and again on Saturday. You used to be able to buy old PSAT's for years and they have always been different.
momof2ky, you mentioned that you "used to be able to buy old PSATs" A few years ago, I ordered old PSAT tests from the College Board website. But I don't see them for sale on the website now. Do they no longer sell the old tests?
