The free typing lessons supply the complete "How to type" package. Animated keyboard layout and the typing tutor graphic hands are used to correct mis-typing by showing the right way to type for your learning and practice experience. Lessons' difficulty gradually raises as it starts from only 2 characters and ends with the entire keyboard. When the lesson ends, you can learn a lot from the practice trends: WPM, accuracy and errors distribution.
Touch typing is the ability to use muscle memory to find keys fast, without using the sense of sight, and with all the available fingers, just like piano players do. It significantly improves typing speed and eliminates errors. Touch typing simply makes you more productive and it is a skill worth learning. However, many people engage in the bad habit of ‘hunt-and-peck’ typing, even those seasoned professionals with years and decades of computer experience. It  is easy to understand, though, as touch typing requires dedicated practice to  learn it well.
Sometimes, it’s just easier to watch someone show you how it’s done. You can find all kinds of educational videos about nearly any coding-related topic nowadays: ex-Googlers sharing solutions on coding interviews, YouTubers livestreaming their coding marathons, and even programming veterans showing you how to troubleshoot a specific error in any language you want.
Want more one-on-one coaching and career prep without doing a full-time bootcamp? Try signing up for the subscription-model certification courses from Udacity or Treehouse, where you have the opportunity to ask a tutor for help instead of suffering your coding mistakes or questions alone. You can’t do much better than the $19 coding classes from Udemy (even less, when there’s a sale)—even full-time bootcamp and computer science students sign up for these classes to supplement their learning. 

I recommend checking out CS Dojo, TheNetNinja, and Harvard’s CS50 YouTube channel. If you don’t have time to search for a perfect coding video or channel, you can also check out LinkedIn Learning’s vast video library for vetted and professional-looking tutorials. While the service’s $30/month subscription fee is nothing to sneeze at, you can binge-watch an unlimited amount of content and topics—making LinkedIn Learning a better deal than other on-demand online classes that come with annoying restrictions.
EdX is another leading online-learning platform that is open source instead of for-profit. It was founded by Harvard University and MIT in 2012, so you know that you’ll learn about cutting-edge technologies and theories. Today, edX includes 53 schools. You probably can’t go wrong with the free Introduction to Computer Science from Harvard University.
