Hello,
about the DLR ATPL questions if you search on prune for Lufthansa Italia you will find a wealth of very very valuable information. that may seem old (2005) but they aren't.
the test you get are the one that they sent you, plus an extra small test at the end. But this test you really can not prepare for. Good news is, that in my opinion it was the easiest of the day.
Other suggestion is to just relax and take each test as it comes, once done forget about it. it seems obvious but it works.
Good luck
