Yeah, I thought it was pretty hard. In my personal experience, I took the first diagnostic test on the online student center about a week ago, got a 7 on verbal, and within about 5 hours afterwards did Test 1 in the verbal workbook and got 32/40, which corresponds to a 10/11. So assuming negligible learning experience between the tests, the test results suggested at least to me that it was pretty hard, even for a TPR test.
