My tip to improve your typing accuracy is to... Cover your hands up with a towel, or anything really. Just don't look at your hands and force yourself to try and type accurately.

When my fingers hurt after too much time on the keyboard, I... Take a short break, relax, and let muscles breath. But to be honest, I can not remember the last time I did have to take a break from typing.

My tip to improve your typing speed is to... Go slowly and try to not race the clock. Read and process accurately the next word. Sit with good posture.
