How long have you been typing? Do you use the correct posture? Do you look at the screen at all times? Looking at the screen can be important, because it slows you down having to look back and forth between the screen and the keyboard. Do you have your fingers shaped like there is a bubble underneath them? This can also be important, because you will have trouble reaching the top and bottom row of the keys. Your wrists should be elevated off the desk as well, so you can reach the top rows as well as not cutting off the circulation in your wrists. Finally, you back should be comfortably straight, not lounging. Your bottom should touch the back of you seat back, and the rest of your back a straight line up from it. Those small, basic things can help improve your keyboarding a huge amount. Practice everyday and have fun!
