The instructor was very good, very encouraging, complimentary and attentive. The course work was advanced for the most part. I found it worthwhile overall and just what I needed.

Good, there is really nothing that stands out bad in any way. Would recommend.

I took the in person class. I learned a bunch. I wish there was more communication regarding the online options. I am glad I did not consider that option because there was no communication that you need two monitors to take the class online. If I had taken the online option, I would have had problems because I only have my laptop monitor.

Every thing went smooth except for online customers whose computer kept freezing for one reason or another. That held the class back, and one girl who came in after 9 was not quite prepared for the class.

The [in person] class was often interrupted by the [on-line] participants that could not easily navigate the remote set up. While the instructor did an excellent job at mitigating the interruptions and responding to the on-line needs, I do think that some valuable time was lost in the process. Perhaps the classes would be more efficient if on-line and in-person were not mixed.

I received ITIL 4 Foundations Training from Jo Blitz Escotal remotely using GoToMeeting. Jo made what could be a dry subject enjoyable. There was much review and he gave us ways to remember the material so that we could pass the test.
