You know , if u feel a little sore on the fingers or knuckles , just put your arms up high , and wriggle your fingers (only do this if your fingers feel sore. ) and if your knuckles hurt just put your left hand into a fist and do the same with the right. With the bottem of your left fist , tap the knuckles on your right hand and vise virsa .

My tip to improve your typing speed is to remember all the things I've learned as a kid in elementary : punctuation , grammar and so on. :) I don't mind if anyone uses this , it only will help you ! :)
