When I take my test random letters that I didn't type randomly appear. I even proved it by typing slow and there were letters that would appear our of no where that I did not type and it would make my speed slow. I usually can type 70 words per minute on this site I can barely get 60 words per minute because of random letters appearing and making my speed go down. Oh and lets also mention that also when I do press a key on my keyboard... Yup you guessed it doesn't show up and speed goes down down down. So screw this site it is garbage do not use it.
