I am enrolled in the MSc AI distance learning program. So far I have completed only one module and currently doing Advanced Maths module. The exam for the first module was proctored online via webcam, it was a hassle-free experience.
The study is mostly reading-based. The reading material is written in a way to make it easier to understand. In reference to books the content is taken from is also provided. The university also provides access to an online library which is great and contains many online library services including IEEE Xplore.
The program is accredited by the German Accreditation Council that makes it a legit Masters degree program. There are live sessions with the tutor as well which gives a chance to ask about anything related to the content provided.
Overall I am happy with the program and it seems well organized. The program cost is inexpensive because they provide some nice scholarship options.
