For the past 9 months, I passed 10 certifications. 6 of them with the help of Tutorials Dojo (AZ-900, AWS Developer Associate, AWS Solution Architect Associate, AWS SysOps Associate, AWS Developer Pro, and AWS Solution Architect Pro). I used their materials as a supplement from UDemy training. They have great content that simulates the actual exam. Each practice test answer (right or wrong) has a proper explanation which refers to AWS actual documentation. It’s also a great way to remember things as AWS has so many services and thousands of documents. Finding them yourself needs a lot of effort and time. Practice tests are more difficult than real ones, which is good. I highly recommend TD, it’s worth every penny you spend. I’m looking forward to my next one.
