Course Reviews
Mark did a very good job going through all of the course material with us, taking time to make sure everyone had a thorough understanding of each area before moving on. He paused for questions or if we were having issues and walked through steps to remedy any problems arising. A very good instructor and the course was fairly comprehensive for entry-level participants (especially me!).

Thoroughly enjoyed this course, the content was really engaging and I feel like I've learnt a LOT from it. I now have a far greater understanding of Linux.
