Well organized training, professionally run training and excellent well qualified Instructor

Friendly, easy to use interface. Was very helpful for labs and following along with class material.

ExitCertified education was extremely helpful for preparing me for the AWS certifications.

The course was good a good refresher and also updated me on some newer AWS products. I would have prefered that we were supplied with training materials that we could keep to review while studying for the exam.

This is a good prep training if you are thinking of getting the professional architect certification.
