I recently passed Swiss stage one as ready entry, which is mostly using the DLR modules which also Lufthansa uses for their screenings.
I solely prepared with the CBTs provided by them.
The actual test is very very similar to these training programs and so they are in my opinion the best form of preparation because you will not be surprised at all.
For me and most of the other candidates who were successful it was not necessary to use any third party training software.
As German is my mother tongue I used books by "Hesse/Schrader" to prepare for the maths part. Dunno if they are available in English, but I'm sure you'll find something similar. Unfortunately the provided maths software was a little bit too easy with insufficient variation of the questions.
All in all the actual questions were not that difficult once you got used (again) to the different tasks.
I was tested mental arithmetics via audio only which was rather easy.
Do not bother too much about the visual memory test. You should focus your training on the 2-back and 3-back part. (During training I counted mentally 1,2 or 1,2,3 when looking at each picture, which should help your brain to find connections more easily - for me it helped, try it)
At the more difficult levels I only tried to remember the colours consciously and not the shape at all. I had around 68%-70% on Level 3.
