I improved my score gradually

I did not do well in the first couple of mock tests. However, i was adamant to score well so i opted to streamline my attempts and gradually i went on becoming better. This helped me score better in the final CCNA Data Center 200-155 certification exam. I scored 895 and was very happy today in the morning because of this. I have never been so confident ever in my life and so am thankful to these practice questions.
