The courses are one of the best practical trainings out there. It is clean, understandable, and explains the necessary background information without having to dig into a topic for hours to understand what’s going on.
This satisfies all requirements for a technical training and it is very affordable! Best quality/price combo. Training material is well structured, practices after each section are great to help understanding the topic, exams are also great practical ones. You actually need to think and learn a bit to pass the exam, however the training covers enough details to pass them without much additional research. There are no pre-defined questions or answers
