The best organization I have worked with.
I have done other courses with other organizations such as yours in the past but I have never found one that is so easy to work through. I am a bit of a technophobe and yet I was really impressed with how well thought through and well presented. One of the things I was impressed with was how there is no waiting for marks or certificates, if you finish and pass a quiz you are 'rewarded' with your mark then your certificate within a moment.
