hi guys,
the dlr test is not so easy but it depend for which airline you do it. phase 1 about 35% succeed phase2 about 60% and phase3 30% so all in all about 7% this case is for LH .
for good preparation look this website
www.pilotenboard.de and ask people there .or .
www.topilots.de .
Atpl questions are 100 ( in my case for about 3 years) , alot of basics but some questions were quite hard . try to prepare with exam database.
good luck.
