He provides the highest level of test consultancy and is an oasis of calm in even the most challenging projects. I know that I can rely on Fergus 100%. I would not hesitate in recommending him."

"I had the pleasure of attending an ISEB Software Testing Foundation course run by Fergus and Aqua Computing. He is an excellent trainer and made the study process both enjoyable and effective; carefully integrating the learning of key concepts with exercises and tests which applied that knowledge to real world scenarios. I highly recommend Fergus and would not hesitate in taking the opportunity to attend another course run by him and Aqua Computing."

"Many thanks for the excellent tuition provided last week. I’m certain that your ability to tune our WebEx sessions “on the fly” to accommodate my rather narrow, but long, experience set was a major contributory factor in my passing my ISTQB Advanced Test Analyst qualification at the first attempt. It really helped me reach an understanding of the processes from my own viewpoint rather than having a rote-learned and unappreciated set of information that would be of little value in my career going forward."
