Here are some reviews of the training vendor.
I liked the pace and the "teach then try" style that was used. It was engaging, we weren't listening to long sets of info then trying to remember it and it made the day fly by. I also retained more as I was instantly engaged with trying the skills myself.

This was a good course to learn the essentials of Captivate as a software program.

The instructor was great and followed the curriculum as per Adobe's book but Dreamweaver is a beast of a software with a high learning curve. I found that this course just scratched the surface and taught me the basics and that I would need more practice and learning to create a simple website with ease. This is not a criticism of the course really but I felt I would personally benefit from a slightly slower pace and an extra day. I didn't know that at the time as I seemed to follow the instructor's instructions well and it seemed to make sense in the classroom but once I got home I felt a little stuck!
