I made use of the complete 90 minutes in every attempt

I practiced using the Cisco 300-220 paid online simulation to evaluate my performance under real exam conditions, with the pressure of time and accuracy. This approach uniquely helped me clear the CBRTHD exam, as I relied on my own methods rather than copying others. Aware of my own insecurities, I can confidently say that today's score is entirely my achievement, and it won't be taken away from me.
