I haven't done the course. I did a full time JEB IT Trainer course, what it offers, that the ICS course doesn't offer is - the chance to teach 'real' students rather than your own group of fellow trainers, and a chance to learn tips on ECDL material from fellow students. We learned as much from each from each other - also the course was over an academic year, so there was time to 'digest' the material. As the previous poster said - you will need to know your stuff inside out before you start.
The ICS course sounds like a good course if you are working full time and are very familiar with the ECDL syllabus.
Good luck with it.
