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.
Codewars adds some quirk to the proceedings by offering free coding classes with a martial arts theme. Solving specific coding “katas” (a term for training exercises in karate) will earn you ranks and honors as you move your way to becoming a bonafide coder. Who said learning to code online couldn’t be fun? Codewars also offers one of the more diverse lists of programming languages. Choose free coding classes on:
Founded in 2012, Coursera has grown into a major for-profit educational-technology company that has offered more than 1,000 courses from 119 institutions. While you can pay for certain programs to receive a certificate, there are a number of free introductory programming courses in various specializations from universities such as the University of Washington, Stanford, the University of Toronto and Vanderbilt.
Coding is all in the details, which is why you need to “celebrate small victories,” as one of our programming professors put it. It takes practice to make each element work on its own, as well as constant testing to ensure each line of code will work with all the rest—without errors. If you don’t do seemingly minor things right like closing a HTML tag, you’d be stuck debugging a simple syntax error rather than writing more impressive and complex code.
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.
