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
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.
