My tip to improve your typing speed is to... have a Mac keyboard. See my explanation on the create a typing test tab. If you're lucky, I might even give some hint's to typing faster on your account!

When my fingers hurt after too much time on the keyboard, I try to go easy on my fingers so I can get more good typing speeds. And remember fast AND steady wins the race guys!
