I have been using this website for quite a while now and one thing I am sure about is that this is the best website for building you typing speed. There sure are many other sites for typing practice but 10fastfingers is the best one out there there are so many option to choose from to how you want to practice or test your skills. It has helped me a lot in building my typing speed form 28 wpm when I first encountered this website to 60 wpm in around 4 months of time and it was a fun way of learning to type while competing with other users of the site at multiplayer typing test or at the typing competitions. My goal is to reach a speed of at least 100wpm in the next 2 months and i hope i will be able to achieve that.
