Is the Unified State Exam (USE) a good or bad thing?

The Unified State Exam (USE) is complete idiocy! I got a score of 50 out of 60 on Russian because I filled in the answer bubbles incorrectly in Part B! Yes, I asked five times how to fill them in! And they didn't even know how to fill in the answer sheets and answered all my questions with, "We don't know, and we shouldn't even be dealing with this! Just read the instructions carefully!" And they were bringing water in plastic cups... This woman handed me one, even though I didn't ask, saying, "Drink this and calm down!" after I had been arguing for 15 minutes... I knew this would happen when I didn't want to take it! Of course, I spilled it, but thankfully it was on the test paper, not on the work I wrote with a gel pen! I asked them 25 times how to fill in the enumeration in Part B, question 8... And they gave me water instead!!!! As a friend told me, I was supposed to use commas... But I didn't, so sad. And they also misspelled my name on the test paper – Natal'ya, even though it's NatalIya... And then they ran around for 2 hours filling out some forms.... And for math, they gave us last year's exam just to pass us (like in a specialized math class... how could we do without it!), and we almost all failed it, even though many of us got into Moscow State University and the Faculty of Mechanics and Mathematics without this USE.
