Course Reviews
Brian has been an excellent instructor/trainer. He has been informative, in-depth, and very patient when teaching us the advanced course on PL/SQL. I really loved how he gave us the room and comfortability to learn well and also, importantly, to take a few short breaks to help us recover into a peak-learning mode.
Akhil - Technical Consultant - Professional Services - October 2023
The course contents included many concepts for advanced features that are usable in different situations. I would definitely recommend John as a really good instructor. He is very experienced, presented many useful examples and he is easily to follow up and understand.
Ergys - Software Developer - Defence
The course provided the exact amount of detail in each area for what I needed. I feel I have drawn a lot out of the course and this is massively improve the work that I carrying out in my day to day work.
Tim - Trainee Application Developer - Defence
Kevin is a greater instructor and very knowledgeable trainer in PL/SQL database development. he has a very good mind to debug coding problems given to him.
Brian - IT
The trainer is a great mentor who uses the training materials to supplement his teaching methods. He demonstrated and created worked examples in front of us, showing us how the code fits together to achieve the task at hand. His explanations were always clear. 10/10 would recommend.
Hayden - Applications Developer - IT
An enjoyable course. The pace and balance between theory, exercises and breaks was spot on. The instructors were very knowledgeable and patient. A good week.
