How to improve both speed and accuracy

I just started practice touch typing Previously, I could not even type without looking at the keyboard Now, My avg speed is 30-40 wpm Accuracy ranges from 85 to 100 It's been 2 weeks since I have started practicing I really want to know how to improve I want to get to 60 wpm if possible with in a week Also, is there any way I can improve accuracy no matter what I do I can't seem to improve even if I type slower ,I always end up mistaking.
