It is more important to have a low error percentage than a higher speed. The low error percentage will be your best guarantee for success in the following lessons. You can follow your progress at the statistics page (just press the button 'Statistics' at the upper right corner) You should strive to do all lessons flawless (or at least with max two percent error) before you go on to the next lesson. If you learn to type flawless a high typing speed will automatically ensue. By the way, the error statistics will only save your best results.
Also, something that I've found is that if you go wrong somewhere instead of mindlessly searching for the error (assuming there are multiple or you don't know the error's location) just start from the beginning and go down seeing that if this works. If you see a break and something disconnects, in all probability that's where the error is. It's all logic.
