Self-Prep Triumph: 88% QSBA2022

Hi,
I am from Singapore and I have finished the QSBA2022 certification with good score.
I have done my preparation without any professional help. I did myself and was able to learn most of the concepts, However, I wanted to be sure if I am ready for the exam and I took this practice test and I was clear that I am ready.
Got 88% in the certification. Thanks.
