Course Reviews

The trainer was fantastic with all his explanation and style of teaching. Thanks

Ambrose - Application Support Analyst - Postal/Distribution - September 2017


The trainer delivered a very good course. He has excellent knowledge of the subject matter and he is extremely succinct explaining complex concepts. I thoroughly enjoyed the course and feel confident I can now better understand and maintain the numerous and varied scripts that we support.

- Applications Developer - Academic - April 2017


The course was very useful indeed and covered the Shell scripting content we require in support. I have learnt how to create scripts, amend and write shell programming which is new and very useful techniques. Due to the way I learn I may have benefitted from further time to digest certain topics before moving onto the next one, which could be the course duration or it moving a little too fast for me. Overall, very good course with a very knowledgeable trainer, who always helped with the tasks and explanations in detail.

Having previously undertaken a similar course in the past I expected this course to not be especially beneficial, however this was not the case at all. I have garnered some very useful new skills and knowledge. The trainer's subject knowledge and delivery are a credit to himself and Stayahead. I was constantly engaged and rarely found myself requiring a repeat of the coursework but when needed he was more than helpful in explaining where I was struggling.
