The exit certified aws course provided a good introduction to the tools available on aws.

The class covered the concepts needed for the AWS Cloud Practitioner Certification.

The platform is very intuitive and easy to navigate. Great tool for learning

great class and packed with material, would have lived to spread it more into many days but overall very informative.

Thank you for training on AWS development. Course was good and encouraging but labs need to be improved and provide more information and ask students to more work than provide solutions.
