Course Reviews
John is the best lecturer I have ever had for a course. He took the time to answer our questions and as an non English speaker, I was glad he took the time to talk slowly and letting me understand everything. I really recommend his course. Very complete and interesting.
Seynabou - Digital Manager - Academic - November 2023
Course was very well run, John was excellent at delivering and making sure everyone understood.
Thomas - database administrator - NHS
Very good course overall. I now have further understanding about the course and feel more comfortable using the UNIX System. A big thanks to the trainer - very friendly character and a very good teacher. Would highly recommend.
Kelvin - Technical Operator - IT
Very clear instruction and guidance, have gained a good understanding of Unix. Both instruction and documentation has been great for me as I had no background knowledge of Unix or programming of any sort. This course will allow me to take on my new job role with greater competence and confidence. I would certainly recommend the course to others who might need it and will be considering more in depth courses in future.
Jonathan - Government
Superb Course, the trainer was brilliant and the details within the course easy to follow and understand.
Anthony - Control-M Admin - Broadcasting/TV/Film/Music
Really enjoyed the course which was quite a surprise as I tend to shy away from "technical" courses. The trainer was very knowledgeable and approachable for the whole 3 days and explained things in a way that was fairly easy to understand.
