I've mostly followed this advice to achieve 95wpm from 78wpm in roughly one month (10 minutes average) https://www.youtu...
I've summarized key points of the video above and I've marked those exercises that helped my accuracy
0. Focus (on accuracy) *1. Slow down in difficult words 2. Focus on the next word you're typing *3. Copy text blindly from a book or kindle 4. 10 minute typing test - think of this as a marathon test 5. 1 minute typing test - think "type as fast as you can for not less than 95% accuracy"
For number 3, I've recently replaced it with just keyhero.com quotes and start over when I make 2 mistakes (instead of using KeyHero's Instant Death)
