Always remember, go for accuracy and consistency, not blazing speed. Typing as fast as you can doesn't do you any good if you type with poor accuracy. Try to aim for at least 96% accuracy. If you make some mistakes, slow down. If you're being super inconsistent with your typing, try to match your speed to a happy middle-ground of consistency and good accuracy; no matter how hard it may be to slow down. Practice a lot, know your keyboard layout, make every keypress pronounced, and stay calm.
