I am very pleased with how the trainings are structured. They are very well prepared and bring a lot of value.
Virtual delivery and coordination of the course was great. It had to be rescheduled several times by ExitCertified was always on top of things.
Good course, and the instruction was also good. The pace could have been a bit quicker, but overall a good course.
Happy with both classes I have taken. One in person, one virtual classroom.
I learned many new topics in this training and labs also very interesting to do.
