If you'd like to know some good tips for improving typing here are some of the best that helped me.
1. Make sure that you are fully confident with touch typing (don't look at the keyboard).
2. Pick a quote or write a quote that is full of easy and common words and constantly type on that ensure that you have a high accuracy and slowly increase speed. Note that meanwhile you can also type normal quotes for getting your hand used to them but repetition is key.
3. After getting confident with typing easy words start on typing normal quotes once a day for about an hour. During this time mainly focus on accuracy and control of your hands on the keyboard speed is not all that necessary it's something that comes along as you get better at typing.
Good luck and God bless.
