I was on the tests last week. And I can say if you use skytest for exercise you are on a good way to pass. Some test are the same. I has some problems with ATPL part and Mathematics, but the rest was ok. At the end they told you if you have passed or not, and they also told you where were you ok and where not. They told me that at Math and the part with weights were a little bit bad but everything else was ok. It is not important to be the best at everything, it is important to be ok at all parts. I learned ATPL from Aviationexam, from 5% of base questions that are opened if you have not payed.
There is enough time for everything, expect for my Mathematics
I am looking forward for the next part.
The only problem is that you have to come to Hamburg more often. The best way would be to have everything in three days.
Best of luck to all who have to go through the first part.
