You should do your touch typing lessons as often as you are capable of without hurting your fingers! As with everything else, regular training gives the best result. Most people will probably get the best result by distributing the lessons to several days in the week rather the doing a lot of exercises in one day. It is a good idea to put your touch type training into a calendar to be sure to remember to do them. If you don't have a calendar you can use the Google calendar which is free and easy to use. In this way it is easier to remember to do your exercises.
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.

And now I'm taking what I've learned about starting successful businesses, contracting, sculpture, water feature construction, and more, and sharing it with the world. It's my mission to help people like you enjoy more success both in your business and in your personal life.
I can’t recommend Harvard’s CS50x Introduction to Computer Science enough. You can audit the course for free via edX and earn a certificate by completing all the assignments, or you can go at your own pace and watch all the lectures posted on Youtube. You can build your own DIY college-level computer science program with this selection of fifteen online courses (many of which are also listed in our Lifehacker U series).
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.
