Course Reviews

Course was very well run. Kevin explained everything clearly and at a pace that was appropriate to my level of understanding. The virtual labs were very helpful, allowing me to practice what I have just learnt.

David - IT - January 2022


Excellent instructor - explained the concepts very well with great visual and practical examples and was very patient and easy to speak with. Questions/exercises were at a good level and have a high repeatability factor because of the way they ere structured/asked, which allows one to keep practicing SQL skills even after the course.

Nyakeh - Data Analyst Apprentice - Manufacturing - December 2021


Many thanks to Marian for such an amassing intro training!

Olga - Customer Support Manager - Leisure - August 2021


Enjoyed the intimate nature of the training and the trainer being willing to answer specific questions

Cameron - Senior Geospatial Analyst - Real Estate - July 2021


Excellent Introduction consolidated learning well with enough practice examples

Ronan - Auditor - Government


Perfect pace for the course, I was lucky enough to be in a small class which meant I could ask all the questions that I liked and we went into further detail where required, or just because it was interesting! I will want to do a follow on course - even more so now that I've had the positive experience.

Jennifer - Operational Performance Manager - Finance
