SC-900 practice tests are simulated in a sense that the timing and also the questions in the tests are kept the same as the actual Microsoft Security Compliance and Identity Fundamentals certification exam. I just had to take up a mock and answer it successfully without any inhibitions. They lead me to reach a state of knowledge and practice that kept my momentum high and practice in place. This has been a great year for me. I recently got the result and i have the passed the certification with 880/1000 which is definitely a good news.
