“I loved taking this course. I have taken a few training classes and they were a bit boring. I liked the fact the trainer (Dube) was very friendly and called on different people. This was a very excellent and well delivered course. It was good fun and informative and well structured. Thank you for everything. I don’t know where to begin and can’t wait for Monday to start applying all the new ideas I have.

“The course was extremely helpful specially for me being new in this QA thing. As an introduction to what QA is it`s absolutely accurate and it involves all the aspects that needs to be known before getting started. So in most cases this is very useful also for people that has been working as QA for years, where actually this type of information gets forgotten or is good to keep it fresh once in a while. The entire course made me fell anxious and happy about starting with this and it also helped me to improve the basic knowledge I had previously for what QA means.
