Welcome

Here you can access beta versions of new courses. These courses are about 95% finished, but cost much less. In return, we ask you for some (anonymous) feedback. By doing so, you will also help other people who suffer from the same problem as you. 

After completion of the course, you will of course receive it later as the final product.

What does beta version mean exactly?

It means there are less potentially causing elements in this version. However, this is most likely completely irrelevant for 99% of the participants.
