Learn to be accurate first then improve speed. Because if you make mistakes all the time the longer it will take you to type. Every time you backspace takes longer than if you slow down just a tad so you can type accurately. I still makes a lot of mistakes but I realize when I slow down to be accurate I actually tend to type slightly faster.
