Course Reviews
Excellent Introduction consolidated learning well with enough practice examples
Ronan - Auditor - Government
Perfect pace for the course, I was lucky enough to be in a small class which meant I could ask all the questions that I liked and we went into further detail where required, or just because it was interesting! I will want to do a follow on course - even more so now that I've had the positive experience.

Really impressed with the instructor, all concepts were explained in a very clear manner and I really enjoyed the day.
