When does class start/end?

Classes begin promptly at 9:00 am, and typically end at 5:00 pm.

Does the course schedule include a Lunchbreak?

Lunch is normally an hour long and begins at noon. Coffee, tea, hot chocolate and juice are available all day in the kitchen. Fruit, muffins and bagels are served each morning. There are numerous restaurants near each of our centers, and some popular ones are indicated on the Area Map in the Student Welcome Handbooks - these can be picked up in the lobby or requested from one of our ExitCertified staff.

How can someone reach me during class?

If someone should need to contact you while you are in class, please have them call the center telephone number and leave a message with the receptionist.

What languages are used to deliver training?

Most courses are conducted in English, unless otherwise specified. Some courses will have the word "FRENCH" marked in red beside the scheduled date(s) indicating the language of instruction.

What does GTR stand for?

GTR stands for Guaranteed to Run; if you see a course with this status, it means this event is confirmed to run. View our GTR page to see our full list of Guaranteed to Run courses.

Does ExitCertified deliver group training?

Yes, we provide training for groups, individuals and private on sites. View our group training page for more information.

The course was overall very good, I would recommend breaking some topics into their own respective courses such as cloudformation as 1 lecture does not do it justice.

ExitCertified was a good platform to use to develop the relevant skills and we learned a lot on how to actually spin up the tools and services we were learning about.

Good material and very knowledgeable instructor. The VM used is very effective and easy to navigate.

Eylem Uysal is an awesome instructor, very knowledgeable and perfect tutor.

Fantastic instructor, good overview of content and ability to answer questions
