The delivery was exceptional.
Columbus - Software Engineer - Government - November 2023
I found Mark extremely good as an instructor. His relaxed manner and vast knowledge gives you a lot of confidence. I found the pace of the course excellent as I never felt rushed to complete the practical exercises. On that note, the practical examples and virtual setup was brilliant. Thank you, I felt like I have really learnt something this week, which doesn't always happen after a training course :-)
