I got the required practice on this site

I was very weak in certain few areas. The questions in the mock tests here covered the entire syllabus of AZ-800. This helped me cover-up the weak areas and even strengthen the topics i knew very well. At the end of the practice of 2 months for Microsoft Administering Windows Server Hybrid Core Infrastructure, i mastered the syllabus and started achieving good score. I am quite relieved with my hard work here.
