Course Reviews

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


Very good teacher. Knows the subject well and is enthusiastic. Facilities are great too.

Scott - 2nd Line It Support Analyst - Government


lots of information covered will be beneficial for us back in the office improving the efficiency of our current sql scripts and alter the way we create new queries going forward

Steven - Analyst - Government


I thoroughly enjoy the Advanced SQL course and learnt a lot in the duration. The most interesting parts was learning about Oracle + REGEX and how we can use that to identify patterns. I will now incorporate that with my day to day usage. The trainer provided clear examples and explained sections very well, where we did not understand he would clarify further.

James - Insurance


Great course material and the tutor was not only very knowledgeable, but also very willing to share his own experience and go the extra mile to ask about our own daily duties to try and tailor scenarios to help us more. Can't wait to progress through to more advanced courses.

Mitch - System Analyst - Postal/Distribution
