So far so good Microsoft PL-400 practice tests

Hii Friends
I was an average student in college so i was very scared whether i would be able to score good in the upcoming Microsoft PL-400 certification exam. But as i started giving mock tests on this site, my improving score made me more and more confident and helped me ace the simulators. 
This is the best way to prepare, according to me. The tests are very very helpful, seriously.
