Do typing practice regularly and be honest about it.

If you already know all the keys, just keep practicing. In my opinion, the near maximum speed for QWERTY is about 90-110 WPM. If you have a job that's very focused on typing or if typing 120+ WPM is somehow a must for you, learn the stenograph. The stenograph takes about 1-3 months to learn all the keys and about a year plus to be proficient. The stenograph works by pressing "chords", or groups of keys together at the same time. Although regular stenographs cost about a thousand dollars plus, you'll be better off with a gaming keyboard, as they not only work with your computer, but also feel really good.
