Course Reviews
Enjoyable course, very good course notes and engaging workshops which helped to develop my understanding. Excellent instructor, John was able to explain the concepts in a way which was easy to understand. All questions I asked were well answered with examples. I would recommend this course.
Vincenzo - Trainee Software Developer - Utilities
This is a complex subject area, and I felt that the information was conveyed very well by Kevin. A lot of effort went into on-screen demos, that reinforced the learning. Presentation of course content and verbal explanations were delivered in a way that was light and fun to be a part of.
Peter - Applications and Reporting Engineer - Government
The course was very informative and expertly delivered, in a virtual environment. John was very knowledgeable and managed to keep a good pace, explaining things well, whilst providing lots of good examples. This course will prove invaluable back in my work environment. Thank you.
Andrew - Government
Fantastic trainer. The class was a mix of technical and non-technical analysts and everyone fully understood each and every part of the training - even though some sections were slightly harder than others. We were given ample time to complete the practical exercises and the trainer was really good and showing us where we went wrong (without making us feeling stupid). I highly recommend this course to anyone wanting to expand their Oracle SQL knowledge.
Graham - Lead Information Analyst - NHS
The trainer was very knowledgeable and very patient, I enjoyed the course very much and will recommend other colleagues within my organisation to use StayAhead for their IT training.
Gavin - Systems Manager - Postal/Distribution
