Overall ExitCertified is a great training provider and the remote learning is as effective as in person.

This was effective way to provide a ton of information in a short time period.

Great company -- easy to sign up and very organized. Loved my teacher and class overall.

Very clean, great cafeteria and well sorted, very kind staff. The bathrooms have to be expanded as they might get crowded sometimes

Both course material and instructor demonstrated a sound foundation on Maximo material
